RF Evaluation and Development Kits, Boards are important ingredients for any wireless engineering endeavor. The 109952-HMC553LC3B is one such critical development solution. The 109952-HMC553LC3B is a frequency-agile, USB2.0 based phase-locked loop synthesizer platform designed to provide RF engineers with fast, accurate frequency and phase-locking. Its small size allows it to occupy minimal space on any standard lab bench.

In terms of application field, the 109952-HMC553LC3B includes frequency tuning, an LNA switch, SMA RF output, key-press control, and a voltage source output. This makes the board suitable for numerous radio frequency (RF) applications, from mobile radio, broadcast, satellite systems, and RF transceivers to wireless communications, measuring and general-purpose signal sourcing. What’s more, the board offers a wide dynamic range of frequency tuning over 970 MHz to 2150 MHz, which is ideal for many commercial, military and emission control applications.

In terms of working principle, the 109952-HMC553LC3B consists of a phase-lock loop (PLL) chip to drive the 32.768 KHz crystal oscillator, which runs as the reference clock. The schematic diagram of the board shows the 8-bit counter side-chaining the PLL to adjust the voltage-controlled oscillator (VCO) frequency. The output frequency can be driven by the PLL, which is controlled by a set of digital control bits. To make the adjustment easier, the board is equipped with an 8051 microcontroller that operates in conjunction with the windows-based GUI. Through this window, the user can interface with the board in a graphical and convenient way.

The 109952-HMC553LC3B also features an onboard power supply, a high frequency (HF) amplifier and a digital frequency synthesizer. This allows the board to provide a wide range of RF signals from DC to several GHz. Furthermore, the 109952-HMC553LC3B includes several external control ports including GPIO and analog control which can be used to adjust the frequency or phase of the signals as well as control the output level of the signal.

To sum up, the 109952-HMC553LC3B is an ideal platform for RF engineers to evaluate, test and develop various RF-related applications. It features a wide range of capabilities, including frequency tuning, an LNA switch, SMA RF output, key-press control and a voltage source output. Moreover, it includes an onboard power supply, a high frequency (HF) amplifier and a digital frequency synthesizer, as well as several external control ports. These features make it an ideal choice for anyone looking to design and develop a wide range of radio frequency applications.
