| High Dynamic Range FET Mixer HMJ9 The Communications Edge TM Advanced Product Information Product Features * +35 dBm IIP3 * No External Matching Elements * * * * * * Product Description The HMJ9 is a high dynamic range, GaAs FET mixer. As an upconverter, this active FET mixer realizes a typical third order intercept point of +35 dBm at an LO drive level of +17 dBm. The HMJ9 comes in a low cost, J-lead package. Typical applications include frequency up/down conversion for receivers and transmitters used in cellular communications systems.
