HMC197A 197AE / v02.1210 GaAs MMIC SOT26 SPDT SwITCh, DC - 3 Ghz Typical Applications Features the hMc197A(e) is ideal for: Low insertion Loss: 0.4 dB • MMDS & wirelessLAN Ultra Small Package: SOt26 • PcMciA wireless cards input iP3: +45 dBm • Portable wireless Positive control: 0/+3V @ 3 µA Functional Diagram General Description the hMc197A(e) 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- 14 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 t minimal amount of Dc current and offer compatibility M with most cMOS & ttL logic families.

HMC197A / 197AE v02.1210 GaAs MMIC SOT26 SPDT SwITCh, DC - 3 Ghz Typical Application Circuit Notes: 1. Set logic gate and switch Vdd = +3V to +5V and use hct series logic to provide a ttL driver interface. 2. control inputs A/B can be driven directly with cMOS logic (hc) with Vdd of 5 to 8 Volts applied to the cMOS logic gates. 3. Dc Blocking capacitors are required for each RF port as shown. capacitor value determines lowest frequency of operation. 4. highest RF signal power capability is achieved with Vdd = +8V and A/B set to 0/+8V.
