Double Balanced Quadrature Subharmonic Cmos Mixer For WCDMA Direct Conversion Receiver
This report describes a sub-harmonic mixer for WCDMA applications. The circuit converts a 2GHz RF signal directly to baseband using a 1GHz LO frequency. The mixer operates in the quadrature double-balanced mode and requires octet-phase (0' , 45', 90' , 135' , 180'...

| description | This report describes a sub-harmonic mixer for WCDMA applications. The circuit
converts a 2GHz RF signal directly to baseband using a 1GHz LO frequency. The mixer
operates in the quadrature double-balanced mode and requires octet-phase (0'
, 45', 90'
,
135'
, 180'
, 225'
, 270'
, and 315'
) local oscillator (LO). However the design of the octet-phase LO is not in the scope of this project. In this project, the inputs representing the LO
signals are obtained from the generators. For linearity improvement, predistortion
compensation and negative feedback scheme are used in the frequency down-conversion
circuits. The mixer achieves a conversion gain of 2dB, 3.69-dBm IIP3,0.69dBm P1dB in
the WCDMA Rx band (2110-2170 MHz). The performance has been verified using
SpectreRF simulation. |
