Functional Diagram
General Description
The HMC197 & HMC197E are low-cost SPDT switches
in 6-lead SOT26 plastic packages for use in general
switching applications which require very low insertion 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 applications 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 HMC221
for same performance in an alternate SOT26 pin-out.

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.

The circuit board used in the final application should
be generated with proper RF circuit design techniques. 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 evaluation circuit board shown above is available from
Hittite Microwave Corporation upon request.
