It is designed to improve the system receiver sensitivity and reduce system design complexity. The module integrates the Low-Noise Amplifier (LNA), the Mixer, and the Image Reject Filter (IRF). It offers industry leading performance of 19.5dB Conversion Gain, 21.5 dBm IIP3, noise figure as low as 5.6dB, and excellent image rejection of 40dB, over a wide operating frequency range from 14GHz to 24GHz with small size of 6.9mm x 3.5mm.

The applications of HMC445LP4ETR covers a variety of wireless applications such as Radar, Mobile Handsets, Wireless broadband, VSAT etc., requiring high performance receive path. It is suitable for 3G, 4G, and 5G Base Station receiver path application.

Working Principle:

The working principle of HMC445LP4ETR is based on the receiver architecture. It includes LNA, Mixer and Image Reject Filter (IRF).the Low Noise Amplifier (LNA) provides gain to the incoming signal passing to the mixer. The mixer combines the incoming signal with a local frequency source to produce the difference frequency. The IRF then helps to reject any interfering signal or unwanted images in the output by providing a reject band between the wanted signal frequencies.

The module also provides two voltage control pins, VCTRL1 and VCTRL2, to enable external control of the gain and noise figure for optimal performance matching in systems with varying conditions. Also there is an additional signal path for RF bypass filtering, helping to further reduce the harmonics and narrow the passband of the RF signal.

Overall, the HMC445LP4ETR is the ideal solution for high sensitivity, low noise, and image rejection performance in the 14GHz to 24GHz frequency range. It helps to reduce the complexity of the system design and improve performance in a wide range of wireless applications.
