What are the key features of HMC311SC70?

  • Wideband DC to 8 GHz operation enables use across a broad RF frequency range in a single compact stage
  • 11 dB gain with 50 Ω characteristic impedance simplifies impedance matching in RF signal chains
  • InGaP HBT technology delivers high linearity with 10 dBm maximum CW input power in a tiny SOT-23 6-pin SMT package

What is HMC311SC70 used for?

HMC311SC70 is well suited for broadband RF amplification in microwave and millimeter-wave systems where gain from DC up to 8 GHz is required. It fits cellular infrastructure, test and measurement equipment, and radar front-end designs needing a low-noise gain block in minimal PCB area. The 50 Ω matched input and output allow direct cascade into most RF signal chains without additional matching networks.

Frequently Asked Questions

What frequency range does the HMC311SC70 cover, and how does that benefit wideband RF designs?

The HMC311SC70 covers DC to 8 GHz, giving designers a single gain block stage that works from baseband through X-band microwave frequencies. With 11 dB of gain and 50 Ω impedance, it eliminates the need for band-specific amplifier replacements across a wide frequency span.

How much input power can the HMC311SC70 handle before compression?

The HMC311SC70 supports a maximum continuous wave input power of 10 dBm, making it suitable for moderate-signal RF paths where the amplifier must remain linear. Operating within this 10 dBm limit ensures the 11 dB gain figure is maintained without driving the device into compression.

Which package does the HMC311SC70 use, and what PCB footprint does it require?

The HMC311SC70 is housed in a 6-pin SOT-23 surface-mount package with manufacturer code HKS-6-1. This compact SMT footprint occupies minimal board area, making it ideal for space-constrained RF PCB layouts in portable and handheld wireless devices.

Is the HMC311SC70 suitable for 5 GHz Wi-Fi or UNII-band amplification stages?

Yes, because the HMC311SC70 operates from DC to 8 GHz, it covers the 5 GHz UNII bands used by Wi-Fi and other ISM applications with margin. Its 11 dB gain and 50 Ω matched port impedance allow direct integration into 5 GHz front-end modules alongside filters and mixers.
