Positive Control: 0/+3V @ 3 µA
General Description
The HMC197B(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-
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
HMC221B(E) for same performance in an alternate
SOT26 pin-out.

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.

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.
