Frequently Asked Questions

What is the insertion loss and isolation specification of the HMC321LP4 across its DC to 8 GHz operating range?

The HMC321LP4 provides a maximum insertion loss of 3.1 dB and a minimum isolation of 20 dB across its DC to 8 GHz operating band. These figures make it suitable for multi-path RF switching in test equipment and radar front-ends where signal integrity is paramount.

How much input power can the HMC321LP4 handle before signal compression becomes significant?

The HMC321LP4 can handle continuous-wave input power up to 26 dBm, with its 1 dB compression point at 23 dBm. This gives designers headroom for high-power RF paths in base station and industrial radar designs operating at 50 Ω impedance.

Which RF switch topology does the HMC321LP4 implement, and how does that benefit phased array antenna designs?

The HMC321LP4 uses an SP8T (single-pole, eight-throw) topology, allowing a single control point to route RF signals from DC to 8 GHz to any of 8 output ports. In phased array antennas this simplifies beam steering hardware by replacing 3 binary switches with one device, cutting board area and insertion loss in the signal path.

In which compact package does the HMC321LP4 ship, and how does this aid dense RF PCB layouts?

The HMC321LP4 ships in the HCP-24-2 QFN package, a leadless 24-pin flat package with an exposed thermal pad. Its small footprint and surface-mount assembly allow tightly spaced RF routing at 50 Ω in phased array modules, multi-band radios, and test systems where board real estate is at a premium.
