Single Positive Supply: Vdd = +5V
Integrated 2:4 TTL Decoder
3x3 mm SMT Package
General Description
The HMC241LP3 & HMC241LP3E are general pur-
pose non-reflective SP4T switches in low cost lead-
less surface mount packages. Covering DC - 4 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 compatibility. 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, T_A = +25° C, For TTL Control and Vdd = +5V in a 50 Ohm System
