Device Overview

General Description

The T3H-20G is a high performance mixer featuring LO/RF from 10 MHz to 20 GHz and IF from 10 MHz to 18 GHz. As with all T3 mixers, this mixer offers unparalleled nonlinear performance in terms of IIP3, P1dB, and spurious performance with a flexible LO drive requirement from +15 dBm to +25 dBm. The T3H-20G is offered in connectorized, surface mount, and drop-in style packaging, suitable for any type of system level integration. The T3H-20G is a form-fit-function replacement for the obsolete T3H-20, built using GaAs diodes instead of Si.
