Another ERLS receiver from Jumper-RC. It’s similar to the ELRS AION-RX-MINI receiver, but this version named Nano also features a 100mWÂ power amplifier (PA). The PA enhances the performance of the receiver. In particular it helps to extend the telemetry range.
More info about a PA: “A Power Amplifier (PA) boosts the outgoing signal strength and extends the telemetry range back to the TX. Without a PA, the power output is limited by the RF chip’s max power output itself (around +13dBm 20mW). It works the same way as turning up the power output on the transmitter module, however it is not adjustable. The receiver’s output can be ran at adjustable power levels given range needs. Most PAs are 20dBm/100mW, meaning the telemetry transmit power can be adjusted to 10, 25, 50 or 100mW.”
