Abstract :
Frequency translation circuits are an integral part of transceiver systems. A novel wideband frequency quadrupler is implemented in 0.15mm pseudomorphic HEMT technology with an ft = 85GHz. The multiplier is split into two bands, to cover 27-34GHz and 35-40GHz. The circuit provides times4 multiplication of the input LO with greater than 30dBc suppression of undesired fundamental and all harmonics over a 24% bandwidth in the low band. The low conversion loss of 5dB is an added advantage coupled with the low power dissipation at 163mW which is an attractive feature of this multiplier. The low power consumption, low conversion loss and high spectral purity makes this chip integral to the requirements of multifunction MMIC transceivers. The novel MMIC quadrupler measures only 4.5times1.5mm
