100MHz-6000MHz LNA +22dBm P1dB: This LNA uses the qorvo QPL9547 which offers superior noise figure , gain and P1dB .
Due to its wide bandwidth it makes a great lab amplifier to be used with spectrum analyzers but also works great for ham radio use .
The unit is small enough to mount directly to a coax relay using a SMA barrel avoiding addiotional cable losses .
A build in LDO allows operation from 6 up to 30V
Since the 9547 is primarily designed for use in cellular infrastructure the noise figure sweetspot is in between 700MHz and 2700MHz , at 1.3GHz W2HRO measured 0.22dB NF , at 2.3GHz the typ NF is around 0.5dB , at 433MHz i measured 0.12dB using a 346A and N8973A at 144MHz NF increases to 0.35dB.

TE Systems 0552G 6 Meter Amplifier: Sold pending funds
The TE Systems Model 0552G is an RF Amplifier subsystem designed to interface between a two-
way transceiver and an antenna. This product uniquely integrates a high power RF amplifier with
a very low noise GaAs FET receive preamp thereby providing performance unachievable
heretofore. During transmit the unit functions by linearly amplifying the transceiver output
signal up to the specified power level. when in the receive mode it performs like an LNA
by amplifying the received signal with minimum noise figure. $300 plus shipping.; Listing #1750576 - Submitted on 11/24/25 by Callsign W8EMD - IP: syn-045-037-215-188.res.spectrum.com; Click to Contact -- Send this Ad to a Friend
