PHA-11+

RF Amplifiers Overview

The Mini-Circuits PHA-11+ is a dual matched wideband amplifier fabricated using advanced E-PHEMT technology. It operates within a frequency range of 50 MHz to 3 GHz and provides a typical gain of 12 dB. The device requires a supply voltage of 5 V with a current consumption of 146 mA. Key performance metrics include a noise figure of 2.7 dB, a P1dB compression point of 20.4 dBm, and an OIP3 of 41.8 dBm. It features an input return loss of 4.5 dB and dissipates 1 W of power. The component is housed in an 8-TDFN package with an exposed pad and supports operating temperatures from -40°C to +85°C.

RF Amplifiers Procurement Notes

Verify the specific suffix (+) indicates RoHS compliance when sourcing. Confirm the package type matches the design footprint requirements. Check the manufacturer's latest datasheet for any updates on testing conditions or recommended bias networks. Ensure the supply voltage range aligns with system capabilities.

RF Amplifiers Selection Notes

Select this component for applications requiring dual-channel matching without external balancing networks. Consider the 12 dB gain and low noise figure for signal chain integration. Evaluate the thermal dissipation capabilities given the 1 W power rating. Compare IP3 specifications against linearity requirements for the target frequency band.

RF Amplifiers Part Context

This part belongs to the PHA series of RF amplifiers from Mini-Circuits. It serves as a direct replacement for the WJ AH11 model. The dual-matched architecture simplifies circuit design by eliminating the need for external phase shifters or hybrid couplers typically required for balanced configurations.

RF Amplifiers Replacement Considerations

The PHA-11+ may be used as a replacement for the WJ AH11. Verify pinout compatibility and electrical parameter equivalence before substitution.
