JFW Industries, distributed in Australia by RFI Industries , has released two solid-state switches.

The 50S-1128 is a 1P2T switch, which covers a frequency range of 800MHz-2000MHz and has a 1.4:1 minimum VSWR. The insertion loss is 0.5dB typical (0.75dB max.) at 800MHz-1000 MHz, 0.75dB typical (1.0dB max.) at 1000MHz-1600MHz and 1.0dB typical (1.25dB max.) at 1600MHz-2000 MHz. The isolation is 45dB typical (40dB min.) at 800MHz-1000MHz and 40dB typical (38dB min.) at 1000MHz-2000 MHz. It switches 50W peak and hot switches 10W average. It is TTL compatible with a switching speed of 25μs (50% TTL to 10% OR 90% RF). The RF connectors available are SMA, TNC, BNC, and N female.

A solid-state switch that allows hot switching of up to 100W is also available. The 50S-1268 is a 1P2T RF switch. It has a frequency range of 100MHz-500 MHz and a maximum insertion loss of 0.5dB. Isolation is 55dB minimum and it is available with SMA, N, BNC, or TNC connectors.
