HMJ9

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.
