HMC197BE v01.1117 GaAs MMIC SOT26 SPDT SWITCH, DC- 3 GHz Typical Applications Features The HMC197BE is ideal for: Low Insertion Loss: 0.4 dB Ultra Small Package: SOT26 MMDS & WirelessLAN PCMCIA Wireless Cards Input IP3: +59 dBm Positive Control: 0/+3V 3 A Portable Wireless Functional Diagram General Description The HMC197BE is a low-cost SPDT switch in a 6-lead SOT26 plastic package for use in general switching applications which require very low insertion loss and very small size. The device can control sig- nals from DC to 3 GHz and is especially suited for 900 MHz, 1.8 - 2.2 GHz, and 2.4 GHz ISM applica- tions with less than 1 dB loss. The design provides exceptional insertion loss performance, ideal for filter and receiver switching. RF1 and RF2 are reflective shorts when Off. The two control voltages require a minimal amount of DC current and offer compatibility with most CMOS & TTL logic families. See HMC221BE for same performance in an alternate SOT26 pin-out.
