W-Band and G-Band Diodes

OVERVIEW

Our planar diodes are available as single devices or as multiple devices arranged in series, anti-series and anti-parallel configurations. These diodes provide state-of-the-art performance and reliability. Under the Diodes tab are pricing charts for our W-Band and G-Band Diodes. Within the chart are links to the specifications for each part name. Notes shown below refer to specifications common to all parts. VDI can provide 2-3 week delivery on diodes. Please call for additional information on other types of diodes.

VDI Notes on Diode Mount and Solder
The notes linked above are some general guidelines and details that may be helpful when flip-chip mounting/soldering VDI diodes to circuits. The procedure noted here is essentially the procedure used by VDI. The VDI diode solder contact pads are Au thin films. Process times and temperatures are variable and depend upon the Customer’s circuits or substrates being used. This outline is simply intended to give some general guidelines for diode flip-chip mounting and soldering.

VDI Notes on Diode Specifications (VDI-1004)
The notes linked above describe how to interpret VDI diode specifications.

All diode orders ship with a specification sheet. Current/Voltage data for each die shipped can be included for a $300.00 surcharge which must be included as a separate line item on the purchase order. One surcharge applies to every order of 500 die or less; above 500 die there is an additional surcharge for every additional 500 die.

*The dynamic range specifications assume that low phase sources are used, like those used in the modern Keysight PNA / PNA-X analyzers
with DDS synthesizers. While compatible, other VNAs may reduce dynamic range.

**WM164 (WR0.65) performance is specified for a TxRx-Rx configuration. Performance of a TxRx-TxRx configuration is estimated to have a
~15 dB degradation of dynamic range and may additionally require the use of a mmWave controller.

^†Test Port Input Powers exceeding the peak Test Port Power of the TxRx or TxRef module will compress the module.

General Notes:

Extension modules are compatible with all modern VNAs. Please consult with VDI to discuss VNA and module configurations that will yield the best performance for your application.

Technical Notes:

1. Test Port Power is typical, reduced power is possible at band edges.

2. Stability is specified for 1 hour after system warm-up, in stable environment with ideal cables.

3. Specifications assume a through measurement with two TxRx heads.

4. Specifications are measured on a Keysight PNA/PNAX with front panel connection at 25°C typical.

5. The dynamic range (RBW=10Hz) is measured by first connecting two TxRx modules together and normalizing the un-calibrated S21 & S12. The heads are then disconnected and terminated with a waveguide short. The RMS average of 10 sweeps of the measured S21 & S12 gives the system dynamic range.

6. Typical Module Dimensions exclude testport (2" standard testport for all modules except WM250 (WR1.0), where a 1" testport is used)

^‡Where noted, Extended Frequency Coverage applies; module performance within the standard band conforms to standard specifications while performance in the extended regions can be degraded as follows:

-The minimum and typical dynamic range is degraded by 10dB or less, compared to the specification for the standard band, with the exception of WR5.1.

-For WR5.1, the minimum dynamic range is 95dB (15dB degradation compared to the standard band specification).

-The test port power typical across the extended band is degraded by 5 dB or less compared to the specification for the standard band.

CAL KITS

Calibration Kits

VDI offers banded waveguide calibration kits for s-parameter calibration of our extension modules. Two different calibration techniques are offered dependent upon the frequency of operation: TRL (Through-Reflect-Line) calibrations for WR28 through WR3.4; SOLT (Short-Open-Load-Through) calibrations for WR2.8 through WR1.0. VDI only manufactures Type B versions of the calibration standards to support both QW (Quarter Wave Delay Shim) and QD (Quarter Wave Delay Short) standards. These standard versions are described here. Information about Type A calibration standards are included in the VNAX Manual. Electronic calibration kit definitions are available for download below.

DUAL SOURCE

Dual Source Module Option

The Dual Source (DS) option for VDI VNAX modules adds a second source module and a directional coupler into the standard TxRx Module (see block diagram below). This enables two-tone measurements to allow users to characterize device linearity. VNAX-DS modules have slightly reduced test port power and dynamic range compared to standard VNAX modules. VNAX-DS modules conform to all other standard
S-parameter performance specifications. Specifications listed below are specific for the DS option. For setup instructions or other information about our VNAX-DS Modules, please Contact VDI. For more information on VDI VNAX Modules, please refer to VDI-707.1 (VNAX Product Manual) located under the Resources tab.

The -3DB Option includes a 3dB combining coupler instead of a 6dB combining coupler. With the -3DB option, the Test Port Power imbalance between Source 1 and Source 2 is reduced while sacrificing maximum test port power compared to the standard configuration.

-The minimum and typical dynamic range is degraded by 10dB or less, compared to the specification for the
standard band.

-The test port power typical across the extended band is degraded by 5dB or less compared to the specification
for the standard band.

*Intrinsic mixer conversion loss is measured before any IF amplification.
**Maximum conversion loss of WR-15, WR-12 and WR-10 SAX-M is 4dB at the
High IF Port after IF amplification.
^† For block down-conversion mode only. Maximum IF bandwidth is limited to 20 GHz when
up-conversion option is added.

Signal Generator Extension Modules

OVERVIEW

Description
Virginia Diodes, Inc. (VDI) Signal Generator Extension (SGX) modules provide high performance frequency extension of microwave signal generators into the THz range. VDI SGX modules offer full waveguide band coverage and are available from WR15 (50 to 75 GHz) to WM-164 (1.1 to 1.5 THz) with additional bands under development. This turn-key, sweepable solution is compatible with any microwave signal generator that meets the input frequency and power requirements.

Certain modules can be configured with rapidly interchangeable components for extended frequency coverage. Click here to contact VDI for more information.

Standard Features
- Full waveguide band coverage
- High test port power
- Unwanted harmonic content is better than -20dBc typical
- TTL controlled ON/OFF modulation up to ~kHz
- Voltage controlled RF Power Control
- 5" x 3.5" x 1.5" enclosure suitable for standalone operation or mounting on optical tables and probe stations
- 9V DC power supply included

Options

- External Micrometer driven variable attenuator (~0-30dB)

- Output horn antenna for free space coupling
- Waveguide test port extensions (1" and 2" available)
- Increased amplitude modulation rate (up to ~300 MHz) with added PIN switch (applies to select Mini SGX modules, contact VDI for more information)
- RF cable

Modular Mini SGX

Consider a Modular Mini Signal Generator Extender (SGX-M) with rapidly interchangeable components. Continuous frequency coverage from 170-1,100 GHz (WR9.0SGX-M) or 140-900 GHz (WR10SGX-M) is possible by purchasing additional multipliers.

Standard, re-configurable and broadband THz Signal Generator Extender Modules (SGX-M) are available. The customer can reconfigure the WR10-base or WR9.0-base system for operation to about 1 THz. See details in tables below.

Contact VDI for more information.
