HMC348LP3 348LP3E / v05.0805 GaAs MMIC SPDT NON-REFLECTIVE CATV SWITCH, DC - 2.5 GHz Typical Applications Features The HMC348LP3 / HMC348LP3E is ideal for: High Isolation: >80 dB @ 5 MHz (50 Ohm) >55 dB @ 1 GHz (50 Ohm) • 75 Ohm Systems CATV Signal Distribution, Cable Modem “All Off” Isolation State E Headend & DBS IF Switching Non-Refl ective Design, 75 Ohm Terminations • 50 Ohm Systems 3x3 mm SMT Package Basestation Infrastructure & Test Equipment T Functional Diagram General Description E The HMC348LP3 & HMC348LP3E are non-refl ective 10 GaAs MESFET SPDT switches in low cost leadless QFN surface mount plastic packages ideal for CATV appliLcations. Covering DC to 2.5 GHz, the switch offers high isolation, low insertion loss, integrated 75 Ohm T terminations and an “all off” state. The switch features M >80 dB isolation at 5 MHz and >55 dB isolation up to O S 1 GHz. The switch operates using complementary - positive control voltage logic lines of +5/0V and S requires a +5V bias supply (Vdd). This switch offers E excellent performance in both 50 Ohm & 75 Ohm H S systems for either SPDT or SPST functions.

T These pins are DC coupled and matched to 75 Ohms. 3, 7, 14 RFC, RF1, RF2 Blocking capacitors are required. External capacitors to ground are required. 8, 13 ACG1, ACG2 Select value for optimal isolation below 500 MEHz. 10 10 B See truth table and control voltage table. L T M 11 A See truth table and control voltage table. O S - S E H Application Circuit S C T I W B S O The value of capacitors C1 & C2 are critical for low frequency isolation performance below 500 MHz. 3300 pF 0402 size capacitors are recommended for optimal isolation down to 5 MHz. If the frequency of operation is above 500 MHz then 100 pF to 300 pF 0402 capacitors will be sufficient.
