Pasternack has released a series of active frequency multipliers that simplify system designs by offering high-output power levels.

These active frequency multipliers are important building-block components used in local oscillator (LO) chains for radar, communication receivers and frequency sources to extend frequencies and achieve optimal performance. 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 (×2) multipliers double input frequencies ranging from 4 GHz to 23 GHz up to desirable mm-wave output frequencies from 8 GHz to 46 GHz. These new designs use highly efficient GaAs PHEMT semiconductor technology with integrated amplifiers that produce high-output power levels up to +17 dBm, with 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 and 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 2.92 mm connectors. All models are RoHS and Reach compliant, and are designed to meet MIL-STD environmental test conditions.
