| High Dynamic Range FET Mixer HMJ8 The Communications Edge TM Product Features * +37 dBm IIP3 * No External Matching Elements * * * * * * Product Description The HMJ8 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 +18 dBm. The HMJ8 comes in a low cost, J-lead package. Typical applications include frequency up/down conversion, modulation and demodulation for receivers and transmitters used in communication systems.
