Product Description
The HMJ9 is a high dynamic range, GaAs FET
mixer. As an upconverter, this active FET mixer
realizes a typical third order intercept point of
+35 dBm at an LO drive level of +17 dBm. The
HMJ9 comes in a low cost, J-lead package.
Typical applications include frequency up/down
conversion for receivers and transmitters used
in cellular communications systems.
