Based on a MMIC design process, the reflective SPDT switch maintains high performance across frequencies, including millimeter-wave bands. It has a typical input P1dB of 23 dBm and port isolation of 23 dB at 50 GHz. The TDSW050A2T operates from ±5-V power supplies with minimal DC power consumption and is controlled with TTL-compatible voltage levels.
The switch withstands 100 krads (Si) TID, making it useful for satellite systems exposed to radiation. It meets MIL-PRF-38534 Class K equivalency for space applications and operates over an extended temperature range of -40°C to +85°C. The TDSW050A2T is supplied as a 1.15×1.47×0.1-mm die for hybrid assembly integration.
The TDSW050A2T RF switch is available now for immediate shipment from Teledyne HiRel and authorized distributors.
