HMC452QS16GE

The HMC452ST89 from Analog Devices Inc. is a general-purpose RF amplifier designed for a wide frequency range of 400MHz to 2.2GHz. It delivers a gain of 9dB and an output 1dB compression point (P1dB) of 31.5dBm, making it suitable for RF transmit chain stages. The amplifier features a noise figure of 6.5dB, ensuring acceptable signal quality for most general radio applications.

This RF amplifier operates on a 5V supply voltage and draws a current of 510mA. It is housed in an industry-standard SOT-89 (TO-243AA) plastic package, designed for surface mount assembly. The HMC452ST89 is suitable for use in base stations, wireless communication systems, test equipment, point-to-point radios, and microwave radio systems, functioning in both commercial and industrial environments. It can be incorporated into either the receive or transmit path of a system.

Selection guidelines suggest this model for applications requiring RF amplification within the 400MHz to 2.2GHz range, with 5V operation and moderate gain and output power. Compatibility with SOT-89 surface-mount designs should be considered. Proper handling as a static-sensitive device and attention to PCB layout, including controlled impedance traces and good ground connections, are recommended for optimal performance and to avoid damage.
