low-noise RF amplifier RF amplifier LNA20MHZ to 3GHZ

Description

low-noise RF amplifier RF amplifier LNA20MHZ to 3GHZ
Product application:
This amplifier has a wide frequency range, high gain, noise coefficient etc, and can be used for a variety of rf receive front-end, antenna connected to the low noise amplifier, can magnify the antenna receives the weak signal in order to expand the receiving distance, increase the communication distance. Widely used in hand-held, car radio, all kinds of remote control, receiver repeater, all kinds of radio receiver, FM radio receiver, receiver, and so on need to low noise rf signal amplification. In addition, due to the amplifier ultra wide bandwidth, more can be used for radio management, test full frequency spectrum detection, EMC electromagnetic compatibility test of the receiving end.
The amplifier by the CNC CNC milling of aviation aluminum alloy, high precision, light weight, appearance through grey conductive oxidation processing, conductivity and electromagnetic shielding effect is very good! Can effectively shield the radiation and isolation from the outside environment radiation! Using radio frequency (rf) power supply port wear heart capacitor, the capacitor can effectively filter out peak power on pulse noise! Real figure is as follows:
Amplifier parameters:
Working frequency: 100 MHZ to 3000 MHZ
Gain: more than 30 db (3 GHZ gain 29 db)
Gain flatness: 33 db gain when 100 MHZ, 3 ghz   29.5db
The maximum output power: + 17 DBM (50 mw)     1 db compression point
Power supply: 5 v current 110 ma

Dimension: 45 * 24 * 15 mm, with four install screw holes on the back
The above test curve is the shopkeeper using vector network analyzer HP8753E test out of the low noise amplifier gain and standing wave ratio curves.
Test, according to a report in 100 MHZ gain for 33 db (blue line), standing wave ratio of 1.54 (yellow line)
Gain of 32.9 dB    500 MHZ, standing wave ratio: 1.02    500 MHZ
Gain of 32.0 dB    1000 MHZ, standing wave ratio: 1.14   1000 MHZ
Gain of 29.8 dB     2000 MHZ, standing wave ratio: 1.19     2000 MHZ
Gain of 26.9 dB      2000 MHZ, standing wave ratio: 1.36     2000 MHZ
