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-lea

ackage. Typical applications include

frequency up/down conversion fo

receivers and transmitters used in cellula

communications systems.
