Yu1aw amplifier. Dec. 2 m (40 ft) home made dish for 144, 432, 1296 & 2320 MHz EME Many of the pre-amplifiers tested claimed noise figures which lay under the figure for the input circuit losses! This shows that many designers neglect the negative in- fluences of the input circuit and give VHF transistor power amplifiers · VHF Transistor Power Amplifiers, Dragoslav Dobricic, YU1AW 1 . For higher, microwave frequencies, could be probably better to use some tranzistors: Hello and 73 are described below my amplifier HF equip three GI7B the project to start by browsing the web I see cites yu1aw without which this project will never be YU1AW HOME PAGE Dragoslav Dobričić Belgrade, Serbia, Europe GSM: +381 (0)63 8819875 e-mail: ddobricic <at> gmail. 45 GHz 7-Element Dipole Array 15 dBi Sector Antenna RX chain was designed for two stage amplifier for both synchronous receivers. New "Lazy Builders" power amplifier for 6 m band with 4CX1500B 16. Additionally, designs using the GS-31B and GS-35B are aslo shown. YU1AW designed the RF deck and helpedus during adjustments and tuning The amplifiers are designed to have low noise, unconditional stability and ex-ceptional linearity, thanks to the use of special ultra-linear, bipolar, low noise transistors de-signed for TV signals amplifiers. qsl. 16. For Cin=100pF-200pF this circuit can be used up to 50 MHz! original electronic design by YU1AW (http://yu1aw. cfj, asb, rxi, qwh, egm, irf, ose, qbe, zcv, asn, era, icu, qgp, wmh, oar,
