Peregrine Semiconductor’s 8GHz Digital Attenuator
RFMW (San Jose, CA) has announced design and sales support for the PE43705, a 7-bit, 31.75dB digital step attenuator from Peregrine Semiconductor. Its internal circuitry manages unequal ON/OFF switch times providing a “glitch safe” design by eliminating the unknown attenuation issue that plagues other DSAs. The PE43705 maintains excellent monotonicity over the entire frequency range and features:
- A wide operational frequency range of 50MHz to 8GHz.
- Up to 31dBm of instantaneous power with a CW power rating of 28 dBm.
- An extended temperature range of -40 to +105° C
