very low insertion loss and very small size. These
devices can control signals from DC to 3 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 HMC197 for same performance in an
alternate SOT26 pin-out. The HMC221E is a RoHScompliant product.

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.

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.
