Peregrine Semiconductor Corp. (San Diego, CA) recently introduced two new integrated products—a True DC switch and an X-band core chip. Built on Peregrine’s UltraCMOS® technology, both products integrate RF, digital and analog components onto a single chip.
With a wide frequency range of 0 Hz to 8000 MHz, the UltraCMOS True DC SPDT switch (PE42020) features high power handling, 30 dBm at 0 Hz and 36 dBm at 8 GHz, and maintains excellent RF performance and linearity from DC through 8000 MHz. Moreover, it can switch DC and AC peak voltages in the range of +10V to -10V at currents of up to 80 mA.
The X-band core chip integrates a seven-bit digital phase shifter, a seven-bit digital step attenuator, high isolation signal-path switching, and a compact digital serial interface control with true CMOS compatibility on a single die. The chip offers a maximum power handling of +18 dBm from 9-10.1 GHz and covers 31.75 dB attenuation range in 0.25 dB steps.
