Peregrine Semiconductor introduced the UltraCMOS PE19601, a monolithic phase and amplitude controller (MPAC) solution for beamforming. This device covers a frequency range of 8 to 12 GHz, and is designed for X-band radar applications including active electronically scanned array (AESA) weather, air-traffic control and military radar.
Peregrine’s UltraCMOS technology platform offers high reliability, repeatability and linearity. High linearity is critical to enabling high-dynamic range, high-sensitivity radar. High dynamic range is the radar’s ability to receive a wide range of signal strengths and levels. This means the radar can be more accurate because it can detect weaker return signals. High linearity improves the sensitivity of the radar and enables it to better detect small objects in cluttered environments.
Ideal for high-density, compact arrays, the PE19601 is offered as a bare wirebond die measuring 2,6 x 4,65 mm, and features linearity of greater than 40 dBm IIP3 and isolation of 50 dB. It delivers power handling of 17 dBm and exhibits low power consumption of 0,001 mA.
The chip contains a 6-bit digital step attenuator (DSA), a 6-bit or 10-bit digital phase shifter (DPS), RX/TX switching and a digital serial interface. The DSA covers a 31,5 dB attenuation range in 0,5 dB steps with a low RMS amplitude error of 0,2 dB. The phase shifter has a 360 degree phase range with a very fine resolution of 5 degrees and RMS phase error of 2 degrees. The PE19601 maintains high attenuation and phase accuracy over frequency and temperature.
