The HMC814-SX is an RF, miscellaneous ICs and modules that is designed to provide high performance and multiple function capabilities used in the most advanced wireless applications. It has been designed to meet the needs of wireless transceiver applications where bandpass filtering, integrated amplifier and automatic calibration functions are required.

The HMC814-SX is designed for 4G Long Term Evolution (LTE) applications. It provides 1-chip solutions for LTE and other advanced wireless applications. It is designed to eliminate the need for external filters, thereby reducing the bill of materials (BOM) counts, board space, and cost.

The HMC814-SX can be used in a variety of applications. It can be used in LTE base station remote radio heads (RRHs) and user equipment. It is also a suitable choice for microwave radio, wireless telemetry, mode conversion, trunking radio, avionics, surveillance systems, and other communication systems.

The HMC814-SX integrates multiple functions in a single chip, including a two-stage power amplifier (PA), an integrated input filter, a programmable gain controller, a single-ended to differential converter, and a digital calibration block.

The two-stage PA provides a high level of efficiency that is required in many base stations and LTE RRHs. The integrated input filter eliminates the need for multiple discrete filters, which can reduce the overall system cost. The programmable gain controller provides greater flexibility and fine control of the output power levels of the PA.

The single-ended to differential converter converts multiple single input signals into differential signals, providing improved gain and extended frequency response. This feature simplifies connection and improves reliability. The digital calibration block provides automatic and manual calibration of the gain levels for both the receive and transmit stages.

The HMC814-SX is an effective solution for a wide range of wireless applications. Its integrated functions reduce the need for external components, reduce board space, and the overall system cost. The programmable gain controller, single-ended to differential converter, and digital calibration block provide improved performance and flexibility for the design of wireless transceiver systems.
