Product Description
Functional Diagram
The HMJ1 is a high dynamic range, GaAs
FET mixer. This active FET realizes a typi-
cal third order intercept point of +39 dBm at
an LO drive level of +17 dBm. The HMJ1
comes in a low cost, J-lead package. Typical
applications include frequency up/down
conversion, modulation and demodulation for
receivers and transmitters used in cellular
communications systems.
