Device Overview

General Description

The T3-12 is a high performance mixer featuring LO/RF from 10 MHz to 12 GHz and IF from 1 MHz to 4 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 +27 dBm. The T3-12 is offered in connectorized, surface mount, and drop-in style packaging, suitable for any type of system level integration.
