LNA for HF: LNA4HF is ready
http://lna4hf.blogspot.com/2014/01/lna4hf-is-ready.html
LNA for HF SDR Upconverters. Thursday, January 9, 2014. Finally the LNA4HF is ready after the holidays break. After the initial shipment we have the firsts batch ready for delivery. The final result is the pre-amplifier for the HF frequencies covering the range from 150khz to 30MHz. The high cut off frequency limitation is due to 5 pole low pass filter at the input. There is the possibility to remove the filter and use the pre-amplifier up to 2GHz. DC power supply: 6-9 V. Consumption : 18 mA. NF : 1-2 dB.
