HMC348LP3E

HMC348LP3 / 348LP3E v05.0805 GaAs MMIC SPDT NON-REFLECTIVE CATV SWITCH, DC - 2.5 GHz SWITCHES - SMT 10 10 - 232 Typical Applications Features The HMC348LP3 / HMC348LP3E is ideal for: High Isolation: >80 dB @ 5 MHz (50 Ohm) 75 Ohm Systems >55 dB @ 1 GHz (50 Ohm) CATV Signal Distribution, Cable Modem “All Off” Isolation State Headend & DBS IF Switching 50 Ohm Systems Basestation Infrastructure & Test Equipment LETE Functional Diagram Non-Reflective Design, 75 Ohm Terminations 3x3 mm SMT Package 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.
