High-reliability DC to 50 GHz wideband 50 GHz RF switch

Teledyne HiRel Semiconductors has announced its latest rad-tolerant wideband 50 GHz RF switch, the model TDSW050A2T, which operates from true DC to 50 GHz. It delivers high RF performance down to zero Hertz, making it ideal for many complex space and defence applications.

Based on a 150nm pseudomorphic High Electron Mobility Transistor (pHEMT) Indium Gallium Arsenide (InGaAs) process, the RF switch is available in a 1.15- x 1.47- x 0.1-mm die ideal for hybrid assembly products. It is qualified over an extended temperature range of –40⁰C to 85⁰C per MIL-PRF-38534 Class K equivalency for space applications.

Leveraging MMIC design techniques that deliver superior performance across frequencies up to millimeter wave bands, the RF switch exhibits low insertion loss, high isolation, fast switching times, and high linearity across a wide frequency band from DC to 50 GHz. It attains an input power 1 dB compression of 23 dBm (typical) and supports 23 dB of port isolation at 50 GHz. The RF switch operates with ±5V power supplies with minimal DC power consumption and is controlled with TTL-compatible voltage levels. The TDSW050A2T is TID radiation tolerant to 100 krad (Si), making it ideal for satellite systems. Class K equivalent element evaluation is performed per wafer.

“To meet the higher operating frequencies associated with many of today’s high-reliability systems, this RF switch supports operation from true DC out to 50 GHz, making it ideal for space, military, and defence applications”, said Mont Taylor, Vice President and Business Development Manager at Teledyne HiRel.
