HMJ8 Datasheet | WJ Communication

Features - +37 d Bm IIP3 - No External Matching Elements - - - - - - Product Description The HMJ8 is a high dynamic range, Ga As FET mixer. This active FET mixer realizes a typical third order intercept point of +37 d Bm at an LO drive level of +18 d Bm. The HMJ8 es in a low cost, J-lead package. Typical applications include frequency up/down conversion, modulation and demodulation for receivers and transmitters used in munication systems.
