HMC798LC4TR

RF Mixers Overview

The HMC798LC4TR is a sub-harmonic mixer IC from Analog Devices Inc., designed for VSAT applications. It operates within an RF frequency range of 24 GHz to 34 GHz, utilizing a local oscillator (LO) frequency of 12 GHz to 18 GHz. The device features a single mixer with a maximum conversion loss of 13.5 dB and an intermediate frequency (IF) range of 0 Hz to 4 GHz. Key performance metrics include an OIP3 of 20 dBm and a P1dB compression point of 9 dBm. It requires a 5 V supply voltage with a typical operating current of 97 mA. The component is housed in a 24-CLCC package with dimensions of 3.9x3.9 mm.

RF Mixers Procurement Notes

Verify the specific suffix LC4 against the datasheet to confirm the package type and pinout configuration. Ensure compatibility with the required 24-CLCC footprint on the PCB layout. Confirm that the supply voltage and current draw align with the system power budget before finalizing the procurement order.

RF Mixers Selection Notes

Select this component when sub-harmonic mixing is required to reduce LO source complexity at Ka-band frequencies. Consider the 13.5 dB conversion loss and 9 dBm P1dB limits for linearity requirements. Evaluate the 24-CLCC package size against available board space constraints.

RF Mixers Part Context

This part belongs to the HMC798 series of sub-harmonic mixers. It is functionally similar to the HMC798ALC4TR but may differ in specific manufacturing lot or minor parameter tolerances as defined by the manufacturer's internal coding standards for the LC4 variant.
