LRR102-VHF LOW NOISE AMPLIFER


VHF LOW NOISE AMPLIFER - LRR102

(UNDER TESTING)




The low noise amplifier shares a common design that is utilized by all LNA’s between 50 and 1000 MHz. Each LNA is custom tuned and optimized for gain and noise parameters in its own specific frequency band of operation. This new design utilizes the latest Low noise technology to produce a LNA that is more selective, more robust to ESD, and more immune to out of band interference. The basic design employs a triple tuned band-pass input circuit with a DC shunt to bleed off static or other external discharges. The MOSFET is biased for high P1dB output which is uncharacteristic of low noise amplifiers. With proper matching and gain management, its low noise characteristics are maintained at low frequency operation. The LRR102 LNA design does not offer any RF bypass switching for transceiver operation and therefore may only be utilized in receive only applications. It is offered with various types of RF connectors combinations. This LRR102 series LNA is ready to be “dropped in” to any pre-existing receive system or to be a component in a newly developed receive system.

The preamp is connected in series between the antenna and the receiver to effectively lower the noise figure of the receiver front end, allowing weaker Signals to be received. The LRR102 series was designed for operation in 50 ohm Systems however; they will operate satisfactorily on 75 ohms as well.

  1. Hello,

    I was wondering if these are ready to be shipped out. Also wanted to know if there is a power injector or something available for this pre-amp?

  4. It will be nice if a band changer or tuner can be added, as the BW is 3 MHz. I would love to use it for FM Band 76 - 108 MHz or at least 88 - 108 MHz... Will it be available soon?
