PMA3-83LN+

RF Amplifiers Overview

The PMA3-83LN+ is a monolithic microwave integrated circuit (MMIC) low noise amplifier manufactured by Mini-Circuits. It operates within a frequency range of 500 MHz to 8 GHz, providing a typical gain of 19.2 dB and a noise figure of 2.2 dB. The device requires a single supply voltage of 6 V with a current consumption of 77 mA. Key performance metrics include a P1dB compression point of 18 dBm and an OIP3 of 28.5 dBm. It is housed in a compact MCLP-12 surface-mount package designed for high reliability.

RF Amplifiers Feature Summary

RF Amplifiers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status directly with the supplier or through the latest datasheet revision notes. Cross-reference the Mouser part number 139-PMA3-83LN for accurate distributor identification and availability checks prior to finalizing procurement orders.

RF Amplifiers Selection Notes

Select this component when wideband coverage from 500 MHz to 8 GHz is required alongside moderate noise performance. The 6V supply requirement distinguishes it from lower-voltage alternatives like the PMA2 series. Ensure system power budget accommodates 77 mA current draw. The MCLP-12 footprint must be validated against PCB layout constraints compared to smaller packages like MCLP-8.

RF Amplifiers Part Context

This MMIC belongs to Mini-Circuits' PMA series of low noise amplifiers, designed for RF and microwave applications. It complements other models in the lineup by offering broader bandwidth up to 8 GHz, whereas variants like the PMA2-33LN+ focus on lower frequency ranges up to 3 GHz. The series utilizes silicon technology for cost-effective mass production while maintaining robust performance standards.

RF Amplifiers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult Mini-Circuits' official selection guides for direct replacements or evaluate the PMA2-33LN+ if reduced bandwidth and lower voltage operation are acceptable trade-offs.
