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

Portable Spectrum Analyzer Extenders (PSAX)

OVERVIEW

Description

Virginia Diodes, Inc. (VDI) Portable Spectrum Analyzer Extension (PSAX) Modules are used to extend the performance of modern handheld / portable spectrum analyzer solutions (e.g. Keysight FieldFox) in the frequency range from 50 GHz through 170 GHz, in frequency bands from WR-15 (50-75 GHz) to WR-6.5 (110-170 GHz). Higher frequency PSAX modules are available. An external battery or power supply may be needed to operate higher frequency PSAX modules.

Direct Connect to Keysight FieldFox Analyzers

The VDI PSAX Module is designed to connect directly to the RF Ports on the Keysight FieldFox Analyzers. The IF connector on the PSAX module can be adjusted laterally to be compatible with the LO and IF port spacings of all Keysight FieldFox analyzers.
