Low noise amplifier for 2m band LNA-2m-QRO. LNA 2m QRO comes in two editions: based on PGA-103+ and based on ATF-531P8. Edition that based on PGA-103+ with built-in bypass relays up to 1200 Watts is listed here. It assembled into milled aluminum case with N-female input and output connectors. Assembling with different connectors in QRO lineup is not possible. Pmax TX bypass: 1200 Watt.
BW(-3 dB): < 15 MHz. Noise Figure: < 0.6 dB. P input: 21 dBm (max). VSWR bypass: < 1.1.
DC voltage: 12 - 13.8 V. Dimensions: 86 mm x 76 mm x 26 mm (with connectors). PGA-103+ documentation in PDF available here. It is no need to worry about the "bypass" of this LNA - just simply connect the unit to the feeder. During RX (LNA DC Power = ON) unit works in "LNA mode". When switching to TX (LNA DC Power = OFF) unit works in "Bypass mode". This unit recommended to use with a sequencer in order to be sure in correct RX/TX switching.
You can find our Sequencer PCB solution in listed items. Please, take a look at this small tutorial. Video tutorial - LNA connection and sequence guide. Never put RF Power on LNA Output with DC Power ON. QRO LNAs can't be powered through the feeder, only via pass-through capacitor on LNA's body.
Working with antennas that have a bad VSWR (> 1.5) can lead the failure of the RF relays. Please, take a look at our other products.
