SPDT CATV Switch SMT, DC - 2.5 GHz

The HMC348LP3(E) is a non-reflective GaAs MESFET SPDT switch in low cost leadless QFN surface mount plastic package ideal for CATV applications. Covering DC to 2.5 GHz, the switch offers high isolation, low insertion loss, integrated 75 Ω 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 Ω & 75 Ω systems for either SPDT or SPST functions.
