Overview
The HMC705LP4TR is a low noise GaAs HBT programmable divider from Analog Devices Inc. This component is housed in a 4x4 mm leadless surface mount package and is designed for high-frequency applications. It can be programmed to divide by any number from N = 1 to N = 17, operating up to 6.5 GHz. The HMC705LP4TR is particularly useful in high-performance, fast-settling synthesizer architectures due to its low phase noise floor and high frequency operation.
