This paper presents a highly integrated 45 GHz phase-locked loop frequency synthesizer. The monolithic circuit consists of a voltage-controlled oscillator with frequency doubler and divide-by-16â€¦ (More)

Presents a dual-modulus prescaler with divide ratios of 256 and 257. The circuit uses static divider stages and differential current-mode logic. AND-gates are merged with flip-flops to achieve highâ€¦ (More)

A frequency quadrupler for frequencies up to 45 GHz uses a pre-production 0.4 /spl mu/m SiGe bipolar technology. Gain is achieved at -15 dBm input power between 24 and 45 GHz with maximum of 7.3 dBâ€¦ (More)

This paper presents a static dual-modulus prescaler as needed for mobile communications with division ratios of 128 and 129. It is manufactured in a 0.5 Â¿m 80GHz-fT SiGe bipolar technology. Theâ€¦ (More)

An active I/Q mixer with integrated quadrature oscillator (QVCO) is discussed. It operates at LMDS frequencies at 28 GHz and converts the input signal to two output signals which differ in phase byâ€¦ (More)
