The HMC348LP3 is a non-reflective GaAs MESFET SPDT switch ideal for CATV applications. It offers high isolation, low insertion loss, integrated 75 Ohm terminations, and an 'all off' state. The switch has >80 dB isolation at 5 MHz and >55 dB isolation up to 1 GHz. It operates using complementary positive control voltage logic lines of +5/0V and requires a +5V bias supply (Vdd). This switch provides excellent performance in both 50 Ohm and 75 Ohm systems for either SPDT or SPST functions.
The HMC348LP3 is a non-reflective GaAs MESFET SPDT switch designed for CATV applications, operating from DC to 2.5 GHz. It features integrated 75 Ohm terminations and an "all off" state, making it suitable for both 50 Ohm and 75 Ohm systems. The device offers high isolation, with >80 dB at 5 MHz and >55 dB at 1 GHz in a 50 Ohm system.
