Figure 4 Measured frequency response of the improved double-layer slot-coupled directional coupler measurements. It was deduced that the measured losses and ripples are caused mainly by the resonance effect of the slot. REFERENCES 1. T. Tanaka, K. Tsunoda, and M. Aikawa, Slot-coupled directional cou
## Abstract A wideband bandpass filter using unpowered, packaged HEMT amplifiers is proposed and implemented. The key idea is to utilize very small parasitic capacitances of the unpowered HEMT as a part of the feedback loop connecting LC resonators. At the input power of โ10 dBm, the 3 dB bandwidth
