Harmonic Dual-Band Diode Mixer for the X- and K-Bands [PDF]
Journal of Electromagnetic Engineering and Science, 2021 This paper presents a new dual-band diode mixer for the X- and K-bands. The proposed mixer consists of a pair of series-connected diodes and a frequency-dependent delay line that operates at 180° and 360° at the X-band of 10.525 GHz and at the K-band of ...
