RF Misc ICs and Modules category includes a wide variety of integrated circuits and modules used for radio frequency communication applications. One of the main features of this category is its versatility since the ICs and modules are usually designed to provide a variety of functions in a single package. One such product is the HMC368LP4E, which is a low-power, high-performance RF synthesizer module in a 9 mm × 7 mm × 1.5 mm, 40-lead surface mount package. It is designed to allow the rapid design and implementation of a complete radio frequency system.

HMC368LP4E Application Field

The HMC368LP4E is a cost-effective RF Synthesizer Module that may be used for a wide variety of applications, such as cellular infrastructure, military and aerospace, analog and digital radio, and VHF/UHF transceivers. It can be used in base station transceivers, mobile phones, automotive handsets, telecommunications systems, GPS systems, WLAN/access points, radio receivers, handheld transceivers, radar systems, and cable modem systems. Furthermore, the high order of spurious free dynamic range (SFDR) makes the HMC368LP4E ideal for applications that require a high level of spurious free performance.

HMC368LP4E Working Principle

The HMC368LP4E is a highly-integrated, low-power PLL-based RF synthesizer module that consists of a main frequency synthesizer, a sub-frequency synthesizer, and an antenna switch. Its architecture is based on a Dual Modulus Prescaler (DMP) and low-power voltage controlled oscillators (VCOs) controlled by a phase-locked loop (PLL). The main frequency synthesizer includes a phase comparator, a loop filter, a charge pump, a DMP, and a programmable reference frequency divider.

The sub-frequency synthesizer includes a second charge pump, a prescaler, and a fractional-N divider, which can be used to generate a three-frequency profile or, in some cases, four-frequency profiles. The VCOs of the HMC368LP4E are selectable by the RF pin, and the modulation input signals (such as a low frequency modulation signal or quadrature modulator) are supplied through the analog inputs of the device. The HMC368LP4E also includes an antenna switch and an external VCO buffer amplifier that can be used to increase the output signal level.

The HMC368LP4E uses advanced technology to ensure low power consumption and minimal phase noise, which is why it is used for cost-effective and power-efficient radio systems. The low power consumption and high performance of this RF synthesizer module make it the perfect choice for cellular infrastructure, military and aerospace, analog and digital radio, and VHF/UHF transceivers.
