Product Description
The HMJ8 is a high dynamic range, GaAs FET
mixer. This active FET mixer realizes a typical
third order intercept point of +37 dBm at an
LO drive level of +18 dBm. The HMJ8 comes
in a low cost, J-lead package. Typical applica-
tions include frequency up/down conversion,
modulation and demodulation for receivers and
transmitters used in communication systems.
