Functional Diagram
General Description
The HMC221 and HMC221E are low-cost SPDT
switches in a 6-lead SOT26 plastic package for
use in general switching applications which require
very low insertion loss and very small size. These
devices 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 per-
formance, ideal for filter and receiver switching. RF1
and RF2 are reflective shorts when “Off”. The two
control voltages require a minimal amount of DC cur-
rent and offer compatibility with most CMOS & TTL
logic families. See HMC197 for same performance in
an alternate SOT26 pin-out.The HMC221E is a RoHS-
compliant product.

Typical Application Circuit

SWITCHES - SMT
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.
