Product Description

The HMJ5 is a high dynamic range GaAs FET

mixer. This active FET mixer realizes a typical

third order intercept point of +35 dBm at an LO

drive level of +17 dBm. The HMJ5 comes in a

low cost, J-Lead package. Typical applications

include

frequency

up/down

conversion,

modulation and demodulation for receivers and

transmitters used in communications systems.
