HMC241LP3E

The HMC241LP3E is a general purpose, non-reflective SP4T switch designed for RF applications from DC to 4 GHz. It is housed in a compact 3x3 mm SMT package, making it suitable for space-constrained designs. This switch offers a low insertion loss of 0.7 dB at 2 GHz and high isolation of 43 dB at 2 GHz. It operates with a single positive supply voltage (Vdd = +5V) and features true TTL/CMOS compatibility. An integrated 2:4 decoder simplifies control, requiring only two control lines.

Key electrical specifications include an insertion loss of 1.2 dB maximum at 4 GHz and isolation of 30 dB at 4 GHz. The return loss in the 'on state' is 18 dB up to 2.5 GHz, and 12 dB in the 'off state' from 0.3 to 4.0 GHz. The part supports an input power for 1dB compression of 26 dBm and an input third-order intercept point of 45 dBm. Switching times are fast, with rise and fall times of 40 ns and turn-on/off times of 100 ns.

Typical applications for the HMC241LP3E include base stations and repeaters, WLAN, WiMAX, WiBro, CATV/DBS, and test equipment. Its surface mount package and integrated decoder simplify integration into various RF systems.
