Pasternack launches series of GaAs pHEMT MMIC active frequency multipliers spanning 8-46GHz

Pasternack Inc of Irvine, CA, USA (which makes both passive and active RF, microwave and millimeter-wave products) has launched a series of active frequency multipliers that simplify system designs by offering high output power levels.

The active frequency multipliers are key building block components used in local oscillator (LO) chains for radar, communication receivers and frequency sources to extend frequencies and achieve optimal performance. The firm adds that they support multiple markets and applications including electronic warfare, electronic countermeasures, point-to-point radio, VSAT radio, test instrumentation and telecom infrastructure.

The PE88X-series active frequency (x2) multipliers double input frequencies ranging from 4GHz to 23GHz up to desirable millimeter-wave output frequencies from 8GHz to 46GHz. The new designs use highly efficient gallium arsenide (GaAs) pseudomorphic high-electron-mobility transistor (pHEMT) technology with integrated amplifiers that produce high output power levels up to +17dBm with what is claimed to be excellent fundamental and harmonic suppression. This can eliminate the need for an external LO buffer amplifier stage and additional support circuitry.

The active frequency multipliers require a single +5V DC supply. Input/output RF ports are matched for 50 ohms and are DC blocked. The compact drop-in package assemblies are hermetically sealed and support field-replaceable 2.92mm connectors. All models are RoHS- and Reach-compliant and designed to meet MIL-STD environmental test conditions.

The new active frequency multipliers are in-stock and ready for immediate shipment. "Active multipliers usually require long manufacturing cycles, but Pasternack offers all three models ready to ship right off the shelf," notes active components product manager Tim Galla.
