| High Dynamic Range FET Mixer HMJ1 The Communications Edge TM Product Information Product Features * +39 dBm IIP3 * No External Matching Elements * * * * * * Product Description The HMJ1 is a high dynamic range, GaAs FET mixer. This active FET realizes a typical third order intercept point of +39 dBm at an LO drive level of +17 dBm. The HMJ1 comes in a low cost, J-lead package. Typical applications include frequency up/down conversion, modulation and demodulation for receivers and transmitters used in cellular communications systems.
