VHF LOW NOISE AMPLIFER - LRR102
SEE NEW UPDATE MODEL ON OTHER PAGE
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.
