Analog Devices' HMC1118 is a general-purpose, broadband, non-reflective, single-pole, double-throw (SPDT) switch in a LFCSP, surface-mount package. Covering the 9 kHz to 13 GHz range, the switch offers high-isolation and low insertion loss. The switch features 48 dB isolation, 0.68 dB insertion loss up to 8 GHz, and a 7.5 μs settling time of 0.05 dB margin of final RF_OUT. The switch operates using positive control voltage logic lines of +3.3 V and 0 V and requires +3.3 V and -2.5 V supplies. The HMC1118 can cover the same operating frequency range with a single positive-supply voltage applied and the negative-supply voltage (V_SS) tied to ground and still maintain good power handling performance. The HMC1118 is packaged in a 3 mm × 3 mm, surface-mount, LFCSP package.
