RF mixers as part of the radio frequency (RF) section, are components that can efficiently convert the frequencies of two signals. The HMC787ALC3BTR is a high-performance mixer that performs RF down-conversion from frequencies ranging from 4.4 to 8.7GHz to basebands of 2GHz below. Depending on the application, it can operate with an LO drive level of +14dBm and delivers hybrid-based double-balanced diode logic. It also provides excellent gain flatness and very low conversion loss of only 7.0dB.

The HMC787ALC3BTR is a robust and reliable device, commonly used in applications where high-precision RF down-conversion is required. It is often used in commercial RF applications, such as satellite transponders, broadband radios, and TV and radio broadcasts. The HMC787ALC3BTR is also commonly used for military and test equipment such as direction finding, data demodulation, and EMC testing.

The HMC787ALC3BTR is constructed of GaAs Monolithic Microwave Integrated Circuits (MMICs). It has an operating frequency range of 4.4 to 8.7GHz with a minimum conversion loss of only 7.0dB. The RF and LO ports are matched to 50 Ohm impedance, and the RF/LO isolation is >50dB. The mixer also has excellent gain flatness of ±2.0dB across the operating frequency range.

This mixer utilizes active circuitry to down-convert a high-frequency signal into a lower frequency using double-balanced diode logic. First, the signal to be down-converted is amplified and sent to the RF port. Then, the Local Oscillator (LO) signal is fed into the mixer’s LO port. This LO signal is phase-shifted so that it is in-phase with the RF signal, causing the desired frequency to be cancelled out. The resulting output signal is a lower frequency than the input. This mixer is relatively efficient and can handle high signal levels, making it an appealing choice for high-performance applications.

The HMC787ALC3BTR is a reliable and high-performance mixer with a wide range of commercial and research applications. Its excellent gain flatness and low conversion loss make it well-suited for many RF-related tasks. Its design makes it an excellent choice for down-converting high-frequency signals, providing excellent results. With this mixer, it is possible to get high-performance RF down-conversion with minimal effort.
