“…Cohn et al and Schneider et al analyzed the harmonic mixing with APDP and demonstrated it has only even-harmonic mixing products in the form of symmetric conduction periods [7], [10]. The EHMs with APDP have been proposed for many applications such as modulators [11], [12], millimeter-wave image-rejection mixers [13], direct conversion mixers [14], [15] as well as millimeter-wave mixers [16], [17]. In this paper, using EHMs based on a pair of APDPs, the direct conversion circuitry is realized to provide both I/Q phase channels.…”

A compact integrated antenna with direct quadrature conversion circuitry for broad-band millimeter-wave communications is proposed. The conversion circuits include two even-harmonic mixers based on antiparallel diode pairs (APDPs). The equivalent circuit of the APDP derived here provides good agreement with the measured data from 17 to 23 GHz. Overall phase and amplitude imbalance between the in-phase/quadrature (I/Q) output channels are less than 1.2 and 1 dB at IFs of 10 and 100 MHz, respectively. An overall RF power conversion loss of 14.6 dB at the quadrature I/Q channels including the antenna is achieved in the frequency range from 39.75 to 40.25 GHz with a local oscillator (LO) power level of 11.8 dBm. LO leakages at 20 and 40 GHz are 31.5 and 44.8 dBm, respectively. In order to demonstrate the system capabilities for broad-band digital communication, a communication link is built with a pair of the proposed front-ends. Data transmission up to 1-Gb/s data rate for quadrature phase-shift keying modulation is demonstrated. Index Terms-Antiparallel diode pair (APDP), broad-band millimeter-wave circuit, direct quadrature conversion, integrated patch antenna.

“…It seems that especially the need for high integration restricts the receiver architecture to the zero-IF structure. Examples can be found in [21], [22], [23] and [24]. Al1 these receivers are designed using standard BiCMOS processes.…”

Third generation wideband CDMA (W-CDMA) systems like UMTS will add broadband data to support video, Intemet access, and other high speed services for untethered devices. They are currently deployed in Japan and will be introduced in Europe in 2002. Despite sufficient RF performance has been assumed in the standardization bodies, especially in mobile devices the RF part is still a limiting factor for the overall system characteristics. Only an integral design approach including both RF and baseband functionalities makes it possible to achieve analog front-ends with sufficient performance. This paper reviews transceiver architectures with respect to W-CDMA and presents some of the recent silicon-based radio frequency integrated circuits for mobile terminals.

“…In order to reduce the LO self-mixing and IM2 problems normally associated with direct conversion receivers, even harmonic mixers have been implemented previously using a well-matched anti-parallel diode pair [3]- [4] or an emitter-coupled bipolar junction transistor pair [SI. In this paper, a 2GHz even harmonic mixer achieves similar performance using a standard digital CMOS technology that is more amenable to emerging system-onchip solutions.…”

An even harmonic mixer implemented in a 0.25pm standard digital CMOS process for applications in 2GHz direct conversion receivers is described. The novel mixer circuit overcomes the classical DC offset problems that degrade the sensitivity performance of direct conversion receivers using conventional mixers. Simulated with a 1% g, mismatch, the new even harmonic mixer achieves excellent DC offset cancellation and IIP2 values of 87dB and +40dBm, respectively. The mixer draws 1.7111~4 from a single 3V power supply.
