Mini-Circuits RF Amplifiers PMA2-43LN+

The PMA2-43LN+ from Quarktwin Technology Ltd. is an ultra-low noise MMIC amplifier designed for applications requiring high sensitivity and dynamic range, such as base station infrastructure, portable wireless, LTE, GPS, GSM, and airborne radar. It operates within a frequency range of 1.1 to 4.0 GHz and features a typical noise figure of 0.46 dB at 1.9 GHz, which contributes to lower system noise performance. This amplifier has a high third-order intercept point (IP3) of 33 dBm at 1.9 GHz, making it suitable for low noise receiver front-end applications. It provides a typical output power of 19.9 dBm at 1 dB compression and is designed to operate on a single 5V supply. The compact 2 x 2 mm package allows for efficient use of space in dense circuit layouts. The PMA2-43LN+ is rated for a maximum input power of +22 dBm for short durations and +14 dBm for continuous operation, ensuring robust performance in typical receiver input scenarios. It also maintains low operating current, which helps keep junction temperatures below 103 ¬8C at 85 ¬8C ground lead temperature, enhancing reliability. The device is RoHS compliant and comes in a plastic package with an exposed paddle for improved thermal contact.
