Functional Diagram
General Description
The HMC241LP3 & HMC241LP3E are general pur-
pose non-reflective SP4T switches in low cost lead-
less surface mount packages. Covering DC - 4.0
GHz, this switch offers high isolation and has a low
insertion loss of 0.7 dB at 2 GHz. The switch offers a
single positive bias and true TTL/CMOS compatibil-
ity. A 2:4 decoder is integrated on the switch requiring
only 2 control lines and a positive bias to select each
path, replacing 4 to 8 control lines normally required
by GaAs SP4T switches.
Electrical Specifications, TA = +25° C, For TTL Control and Vdd = +5V in a 50 Ohm System
