Transceiver

A transceiver comprising:

• a receiver including a receiver-side demodulator for converting a received RF receive signal into an analog receive signal;
• and
• a transmitter including a transmitter-side modulator for converting an analog transmit signal into an RF transmit signal,
• wherein the receiver further includes
• a low-noise amplifier for amplifying the RF receive signal,
• a receiver-side voltage-controlled oscillator,
• a receiver-side divider for frequency-dividing a receiver-side oscillating output signal produced by the receiver-side voltage-controlled oscillator thereby to produce first and second receiver-side local signals to be supplied to the receiver-side demodulator, and
• an analog-to-digital converter for converting an analog receive signal produced in the receiver-side demodulator and output through an output thereof into a digital receive signal,
• wherein a dividing factor of the receiver-side divider is set to a non-integral number larger than one,
• wherein the receiver-side divider having the dividing factor set to the non-integral number is composed of a logic divider which performs a logic operation thereby to produce the first and second receiver-side local signals differing in phase,
• wherein the first and second receiver-side local signals produced by the receiver-side divider make a pair of non-quadrature local signals having a phase difference of 90° plus a predetermined local offset angle,
• wherein mixing of an RF amplified receive signal from the low-noise amplifier and the pair of non-quadrature local signals from the receiver-side divider is performed in the receiver-side demodulator of the receiver,
• wherein the analog receive signal is formed by outputs of the receiver-side demodulator of the receiver according to non-quadrature demodulation as a result of the mixing,
• wherein the analog receive signal consists of a pair of non-quadrature receive signals having a phase difference of 90° plus a predetermined receive signal offset angle, and
• wherein the receiver further includes a phase-shift unit for converting the pair of non-quadrature receive signals into a pair of quadrature shifted receive signals having a phase difference of about 90° on an analog basis.
