Low insertion Loss: 0.4 dB Ultra Small Package: SOt26 input iP3: +45 dBm Positive control: 0/+3V @ 3 µA Electrical Specifications, TA = +25° C, Vctl = 0/+3 to +8 Vdc, 50 Ohm System Typical Applications the hMc197A(e) is ideal for:

  • MMDS & wirelessLAN
  • PcMciA wireless cards
  • Portable wireless the hMc197A(e) is a low-cost SPD t switch in a 6-lead SO t26 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 D c to 3 G hz and is especially suited for 900 M hz, 1.8 - 2.2 G hz, and 2.4 G hz 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 D c current and offer compatibility with most cMOS & ttL logic families.

Set logic gate and switch Vdd = +3V to +5V and use hct series logic to provide a tt L driver interface. 2. control inputs A/B can be driven directly with c MOS logic (hc) with Vdd of 5 to 8 Volts applied to the c MOS logic gates. 3. Dc Blocking capacitors are required for each RF port as shown. c apacitor value determines lowest frequency of operation. 4. h ighest RF signal power capability is achieved with Vdd = +8V and A/B set to 0/+8V. Evaluation Circuit Board the circuit board used in the final application should be generated with proper RF circuit design tech - niques. Signal lines at the RF port should have 50 Ohm impedance and the package ground leads and package bottom should be connected directly to the ground plane similar to that shown above. the eval- uation circuit board shown above is available from hittite Microwave corporation upon request.
