Original Press Release:

Richardson RFPD Introduces New 8-12 GHz Monolithic Phase & Amplitude Controller for Radar and Beamforming Networks from Peregrine

PE19601 consists of a digital step attenuator (DSA), a phase shifter and RX/TX switching

Richardson RFPD, Inc. announced today the availability and full design support capabilities for a new 8–12 GHz monolithic phase and amplitude controller (MPAC) from Peregrine Semiconductor Corporation.

The PE19601 is a HaRP™ technology-enhanced MPAC-beamforming device designed for radar and beamforming networks. It consists of a digital step attenuator (DSA), a phase shifter and RX/TX switching. This functionality is intended for the amplitude and phase control of signals to individual elements in an electronic scanning phased antenna array.

The new MPAC offers a maximum power handling of +17 dBm up to 12 GHz and covers 31.5 dB attenuation range in 0.5 dB steps. The phase shifter offers 360° of phase range with a resolution of 5.6°. The device provides a serial interface to control the attenuation, phase and RX/TX switching. It maintains high attenuation and phase accuracy over frequency and temperature and exhibits low power consumption.

The PE19601 is designed for X-band radar applications including active electronically scanned array (AESA) weather, air-traffic control and military radar.

Additional key features of the PE19601 include:

  • Broadband operation with 50Ω impedance
  • 6/10-bit phase shifter
  • 6-bit attenuation
  • Input IP3 of +40 dBm
  • Bare wirebond die
