Low Insertion Loss: 0.4 dB Ultra Small Package: SOT26 Input IP3: +45 dBm Positive Control: 0/+3V @ 10 uA Electrical Specifications, TA = +25° C, Vctl = 0/+3 to +8 Vdc, 50 Ohm System Typical Applications The HMC197 / HMC197E is ideal for:

  • MMDS & WirelessLAN
  • PCMCIA Wireless Cards
  • Portable WIreless The HMC197 & HMC197E are low-cost SPDT switches in 6-lead SOT26 plastic packages for use in general switching applications which require very low inser- tion loss and very small size. The device can control signals from DC to 3.0 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 fi lter and receiver switching. RF1 and RF2 are refl ective shorts when “Off”. The two control voltages require a minimal amount of DC current and offer compatibility with most CMOS & TTL logic families. See HMC221 for same performance in an alternate SOT26 pin-out.

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.
