Space-saving PIN switches feature integral TTL drivers

Manufactured by L-3 Narda Microwave, the SM-DHS series connectorised PIN switches are supplied in hermetically sealed packages and are aimed particularly at the military, aerospace and telecomms sectors.

The devices operate over the frequency range 2-18GHz, with a switching time of 25ns, a maximum VSWR of 1.8:1 and insertion losses as low as 1.7dB.

Available in a choice of four different models, the switches can be specified with reflective or absorptive operation, SPST or SPDT configuration and a power handling capability of either 200mW or 500mW. All models incorporate reverse-voltage protection for the integral TTL drivers.

Package sizes (excluding connectors) are either 14.98 x 13.46 x 4.83mm or 17.53 x 13.46 x 4.83mm depending on model, and the switches have an operating temperature range of -54 to 95degC.
