The LNA schematics presented are based on Infineon Silicium-Germanium transistors.
1 - Wideband LNA - Frequency Range 100MHz to 4GHz, Gain = 20dB
2 - Wideband LNA - Frequency Range 100MHz to 4GHz, Gain = 20dB
3 - Wideband LNA - Frequency Range 100MHz to 1.5GHz, Gain = 20dB
4 - Wideband LNA - Frequency Range 100MHz to 1.5GHz, Gain = 15dB
5 - Wideband LNA - Frequency Range 100MHz to 2.5GHz, Gain = 32dB
6 - Wideband LNA - Frequency Range 100MHz to 4GHz, Gain = 30dB
7 - Narrow-band LNA - 144MHz to 146MHz, Gain = 22dB, NF = 0.9dB
8 - Narrow-band LNA - 430MHz to 440MHz, Gain = 22dB, NF = 0.8dB
9 - Narrow-band LNA - 1295MHz, Gain = 18dB, NF = 0.9dB
10 - Narrow-band LNA - 2.4GHz, Gain = 22dB, NF = 0.9dB
