MICROWAVE CORPORATION HMC172QS24 V01.0101 GaAS MMIC SP6T SWITCH DC TO 2.5 GHz FEBRUARY 2001 Features LOW INSERTION LOSS (1 GHz): 0.6dB INTEGRATED 3:6 DECODER 24 LEAD QSOP PACKAGE General Description The HMC172QS24 is a low-cost SP6T switch in a 24-lead QSOP package for use in antenna diversity, switched filter banks, gain/attenuation selection, and general channel multiplexing applications. The switch can control signals up to 2.5 GHz and is especially suited for 800-1000 MHz and 1700-2000 MHz basestation applications. A 3:6 decoder is integrated on the switch, requiring only 3 control lines and a negative bias to select each RF path. The 3:6 decoder replaces 12 control lines normally required by GaAS SP6T switches. Switch outputs are reflective shorts when "off". The QSOP24 package occupies the same area as a 14-lead SOIC. See positive bias/TTL SP6T version HMC252QS24. 7 SWITCHES Guaranteed Performance For 0/-5V Control and Vee = -5V in a 50 Ohm system, -40 to +85 deg C Parameter Inser tion Loss Frequency DC DC DC DC DC DC DC DC - 0.5GHz - 1.0GHz - 2.0GHz - 2.5GHz - 0.5GHz - 1.0GHz - 2.0GHz - 2.5GHz 36 31 22 19 19 7 5 Min.
