Millimeter-Wave & THz Systems
VDI offers a wide variety of transmit and receive systems covering the 70-2000 GHz spectrum. These systems incorporate VDI's frequency-extension and mixer components coupled with commercially available microwave oscillators and amplifiers.
Transmit systems are configured as:
a) AMC: Amplifier-Multiplier- Chains (AMC) requiring a Customer low frequency input signal, or
b) Tx: Transmitters (Tx) having the base frequency oscillator (or synthesizer) as an integrated part of the system.
Receiver systems are configured as:
a) MixAMC: Mixer-Amplifier-Multiplier- Chains (MixAMC) requiring a Customer low frequency local oscillator (LO) input signal, or
b) Rx: Receivers (Rx) having the base frequency local oscillator (or synthesizer) as an integrated part of the system.
Standard AMCs & MixAMCs have been developed to provide high performance frequency multiplication and downconversion for full waveguide band coverage. These systems can be used to extend traditional spectrum analyzers and signal generator into the THz and mm-wave ranges.
Transmit systems are designed for either high-power or broadband operation. High Power systems use VDI D-series X2 multipliers (ie D52, D100, etc) to achieve maximum multiplier efficiency and power handling. Full waveguide band transmit systems utilize VDI WRx2 and WRx3 multipliers having lower efficiency but broadband capability. VDI receiver systems incorporate broadband VDI sub-harmonic mixers (ie WR2.8SHM, WR1.5SHM, etc) with broadband local oscillator (LO) multiplier chains. A single-switch DC power supply & cable, electronic output power control (0-5 VDC input) and electronic input (TTL) AM modulation are standard features. System frequency and power is unique and built to customer specifications. VDI has built and delivered hundreds of custom transmit and receive systems to customer specifications.
Standard, re-configurable and broad-band THz AMCs are available. The customer can reconfigure the WR10-base or WR9.0-base system for operation to about 1THz. See details in table below.
Please review some example systems as presented in the table below. Systems are available for any band within the 70-2000 GHz spectrum. The examples shown are a small subset and present some general system photos, layout and details. Contact VDI today to discuss frequency bands, input and output RF powers, phase-locking, noise temperatures and other specifications.
