説明
An effective way to boost power gain without noise figure degradation in a cascode low noise amplifier (LNA) is demonstrated at 4GHz using 0.35μm SiGe HBT technology. This approach maintains the same current consumption because a low-pass π-type LC matching network is inserted in the inter-stage of a conventional cascode LNA. 5dB gain enhancement with no noise figure degradation at 4GHz is observed in the SiGe HBT LNA with inter-stage matching.
