Features
Low Insertion Loss: 0.5 dB @ 2.0 GHz
Non-Reflective Design
Integrated 2:3 TTL Decoder
“All Off” Isolation State
Single Positive Suppy: Vdd = +5V
16 Lead QSOP SMT Package
General Description
The HMC245QS16 is a low cost non-reflective SP3T
switch in a 16-lead QSOP surface mount package.
Covering DC to 3.5 GHz, the switch offers 30 to 40 dB
isolation and a low insertion loss of 0.5 dB. A 2:3 TTL/
CMOS compatible decoder is integrated on the switch
requiring only 2 control lines and a single +5V bias to
select each path, replacing 6 control lines normally
required by GaAs SP3T switches.
Electrical Specifications,
T = +25° C, For TTL Control and Vdd= +5V in a 50 Ohm System

* Circuit Board Material: Rogers 4350
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 imped-
ance and the package ground leads 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.
