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.
