RF Misc ICs and Modules are typically utilized for specialized communications and industrial electronics to provide better performance and integration of otherwise discrete components. The HMC747LC3CTR-R5 RF IC (Integrated Circuit) is an example of a highly specialized RF IC. This particular IC is a low noise harmonic generator / mixer, specifically designed for use in mobile / cellular communication systems from 800-2500MHz.

The HMC747LC3CTR-R5 reduces the parts count associated with converter designs in cellular base station applications, providing higher performance and significantly simplified board layouts. It includes on-chip LO driver amplifiers, an RF shielding can as well as full input / output differential ports. It also contains excellent linearity performance over the full frequency range.

The HMC747LC3CTR-R5 provides a low conversion loss of less than 10dB. It offers the benefit of improved LO-to-RF isolation and high dynamic range. The device is comprised of active harmonic mixer cells designed to efficiently up-convert or down-convert signals from 800-2500MHz with a harmonic spacing of 200MHz. The device also offers noise and spur performance that meets the requirements of today’s cellular systems.

The working principle of the HMC747LC3CTR-R5 is based on the fact that an ideal mixer is a non-linear device, meaning it does not maintain the phase relationship between the input and output signals. When an RF signal is applied at one port (called the LO port) and DC at the other port (called the IF port), the high frequency signal present at the LO port is rectified, creating new harmonic products at the output. These harmonic products are commonly referred to as up-conversion or down-conversion, depending on which port is used for the DC.

Specifically, the HMC747LC3CTR-R5 is a low noise harmonic mixer that converts RF signals from 800-2500MHz with a harmonic spacing of 200MHz. The device features an on-chip LO receiver amplifier and polyphase filter to enable excellent LO-RF / harmonics rejection. The device provides excellent performance in terms of speed, linearity and selectivity. It is generally used in applications such as mobile / cellular communication systems, point-to-point radios, etc.

The HMC747LC3CTR-R5 is also highly suitable for use in applications where low power consumption is desired. It requires very little current compared to conventional mixing techniques and can be operated over the temperature range of -40 to +85°C.

In summary, the HMC747LC3CTR-R5 is a low noise harmonic generator / mixer that is specially designed for use in mobile / cellular communication systems from 800-2500MHz. It provides excellent linearity performance over the full frequency range and excels in terms of low power consumption and wide temperature range operations. It is suitable for applications such as point-to-point radios, etc.
