HMJ4-PCB

High Dynamic Range FET Mixer HMJ4 The Communications Edge ™ Product Features • +36 dBm IIP3 • No External Matching Elements • • • • • • Product Description The HMJ4 is a high dynamic range, GaAs FET mixer. This active FET mixer realizes a typical third order intercept point of +36 dBm at an LO drive level of +17 dBm. The HMJ4 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.
