Low Insertion Loss: 0.6 dB
• ISM/Cellular Portables/Handsets
High IIP3: +65 dBm
• Automotive Telematic Applications
High Input P0.1 dB: +40 dBm Tx

Ultra Small Package: SOT26
Functional Diagram
General Description
The HMC446 & HMC446E are low-cost SPDT switches in 6-lead SOT26 packages for use in transmitreceive applications which require very low distortion
at high signal power levels, up to 10 watts. The
device can control signals from 824 - 894 MHz* and
is especially suited for cellular booster and automotive telematic applications. The design provides
exceptional P0.1 dB of +40 dBm and +65 dBm IIP3
on the Transmit (Tx) port. The Tx port is a reflective
open when “Off” while the Rx port is a reflective short
when “Off”. On-chip circuitry allows single positive
supply operation at very low DC current with a single
control input (Vctl).

[1] Reference this number when ordering complete evaluation PCB
The circuit board used in the final application
should use RF circuit design techniques. Signal
lines should have 50 ohm impedance while the
package ground leads should be connected directly
to the ground plane similar to that shown above.
A sufficient number of via holes should be used to
connect the top and bottom ground planes. The
evaluation circuit board as shown is available from
Hittite upon request.
