Device Overview

General Description

The T3-0838G is a high performance mixer featuring LO/RF from 8 to 38 GHz and IF from 10 MHz to 10 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 +13 dBm to +25 dBm. The T3-0838G is offered in connectorized and drop-in style packaging, suitable for any type of system level integration. The T3-0838G is a form fit function replacement for the obsolete T3-0838, built with GaAs diodes instead of Si.
