HMC977LP4E, I/Q DOWN CONVERTER, 20-28GHZ, HQFN-24
|4 030||×||=||4 030|
The HMC977LP4E is a compact GaAs MMIC I/Q Down Converter which operates between 20 to 28GHz. Down-converter provides a small signal conversion gain of 14dB with a noise figure of 2.7dB and 21dBc of image rejection. The HMC977LP4E utilizes an LNA followed by an image reject mixer which is driven by an active x2 multiplier. The image reject mixer eliminates the need for a filter following the LNA and removes thermal noise at the image frequency. I and Q mixer outputs are provided and an external 90° hybrid is needed to select the required sideband. The HMC977LP4E is a much smaller alternative to hybrid style image reject mixer down-converter assemblies.
