RF Switches Offer Expanded Power, Low Insertion Loss at Higher Frequencies
The latest high-power RF switch products from Finwave Semiconductor, which combine the performance advantages of gallium nitride (GaN) with the scalability and cost efficiencies of silicon manufacturing, deliver fast switching and broadband performance at high frequencies.
Supporting a broad range of applications, the RF switches come in compact 4- × 4-mm QFN packaging designed for SWaP-C (size, weight, power, and cost) requirements in aerospace and defense systems. Leveraging Finwave’s latest GaN-on-Si process technology, the new devices integrate advanced driver functionality to enable smaller form factors, lighter system weight, improved power handling, and lower overall system cost.
The FW2106, FW2107, and FW2108 single-pole, double-throw (SPDT) switches feature enhanced continuous wave (CW) and pulse power handling with expanded frequency coverage for broadband RF applications. The W2109 is an ultra-broadband SPDT switch operating from 300 MHz to 18 GHz with 6-W CW and 12-W pulse power handling, optimized for electronic warfare and wideband communications systems.
The FW2124 is designed for X-band radar and satellite communications applications, delivering 8-W CW and 16-W pulse power handling. The FW2118 and FW2110 are switches for applications that need to minimize insertion loss, supporting up to 12- and 4W CW power handling, respectively, and pulse power handling up to 80 W. The FW2198 is a high-performance single-pole, four-throw (SP4T) switch supporting 20-W CW and 40-W pulse power handling at frequencies up to 10 GHz.
Finwave switch products are also now available as X-MWblocks from X-Microwave, including the FW2001, FW2002, and FW2003. They support power handling up to 30 W and frequencies up to 12 GHz.
