General Description
The HMC348LP3 & HMC348LP3E are non-reflective
GaAs MESFET SPDT switches in low cost leadless
QFN surface mount plastic packages ideal for CATV
applications. Covering DC to 2.5 GHz, the switch offers
high isolation, low insertion loss, integrated 75 Ohm
terminations and an “all off” state. The switch features
>80 dB isolation at 5 MHz and >55 dB isolation up to
1 GHz. The switch operates using complementary
positive control voltage logic lines of +5/0V and
requires a +5V bias supply (Vdd). This switch offers
excellent performance in both 50 Ohm & 75 Ohm
systems for either SPDT or SPST functions.
