HMJ2

High Dynamic Range FET Mixer HMJ2 The Communications Edge ™ Product Features • +37 dBm IIP3 • No External Matching Elements • • • • • • Product Description The HMJ2 is a high dynamic range, GaAs FET mixer. This active FET mixer realizes a typical third order intercept point of +37 dBm at an LO drive level of +17 dBm. The HMJ2 comes in a low cost, J-lead package. Typical applications include frequency up/down conversion, modulation and demodulation for receivers and transmitters used in PCS systems.
