摘要： A radio receiver is configurable to operate in both low-IF and zero-IF modes with maximum re-use of of analogue and digital circuitry between modes. The receiver comprises a quadrature down-converter (108,110,112,114) for generating in-phase (I) and quadrature (Q) signals at an intermediate frequency and a complex filter (516) for performing image rejection filtering.In the low-IF mode, one of the outputs (Q) of the filter (516) is terminated, the other (I) is digitised by a non-complex ADC (520), then the digital signal is filtered and decimated. Quadrature-related IF signals are then re-generated before down-conversion and demodulation.In the zero-IF mode, both outputs of the filter (516) are digitised and processed in parallel before demodulation.By enabling analogue-to-digital conversion and channel filtering to be performed at low-IF on non-complex signals, use of just two non-complex ADCs (120,1620) is possible, thereby avoiding duplication of circuitry and providing significant power savings.

摘要： A phasing receiver includes a quadrature mixing arrangement for frequency converting an input or high IF information signal to a pair of quadrature related low IF signals. The low IF signals are applied to a polyphase filter which functions as a low pass and adjacent channel rejection filter. One or more elements effecting a fine adjustment of relative phase away from quadrature and/or relative amplitude away from equality of the low IF signals are incorporated in information or oscillator signal paths in or about the mixing arrangement or a superhet stage preceding the quadrature mixing arrangement. These elements effect a predistortion of relative phase and/or relative amplitude of the low IF signals in order to compensate for mismatches in an input stage of the filter, and thereby improve image rejection by the filter.

摘要： An integrated receiver in which in order to permit ac-coupling between stages and to remove the effects of strong directly detected amplitude modulated interfering signals lying within the input band of the receiver, the input signal is frequency down converted using a local oscillator signal which provides an intermediate frequency (F.sub.if) which lies above the frequency of the directly detected interferer (F.sub.AMP). The outputs from the frequency down converters (14, 16, 18, 20) are ac coupled to filtering means the outputs of which are applied to an equalizer (52). The filtering means may comprise a polyphase filter (50), the frequency response of which is distorted by the ac coupling capacitors (54, 56). By applying the outputs of the filtering means to the equalizer (52) substantially all the distortion introduced by the ac coupling capacitors (54, 56) on the filter response is removed to provide an acceptable signal for detection and recovery of the modulating signal.

摘要： An automatic gain control strategy for zero IF receivers in which the gain of low pass filters (20,22) is altered whilst keeping their bandwidths substantially constant. The low pass filters (20,22) are implemented as gyrator filters, each of which comprise at least one pair of transconductors, the ratio of the transconductances of which are adjustable in such a manner as to maintain the product of their transconductances constant. An electronic signal for adjusting the ratio of the transconductances is derived from an estimate of the instantaneous signal amplitude of the received signal.

摘要： A combined current difference and operational amplifier circuit (10) for use either as or in a filter embodied in an integrated receiver includes inputs (I.sub.A and I.sub.B) for oppositely phased current signals which are applied to a current mirror circuit formed by first and second NPN transistors (Q1,Q2) having their bases connected to a junction (20). Equal value resistors (R1,R2) are serially connected in the emitter circuits of the first and second transistors, respectively and the current inputs are coupled to the free ends of the resistors. The base-collector path of a third NPN transistor (Q3) is connected between the free end of one of the resistors (R1) and the junction (20). A current difference signal (i.sub.b -i.sub.a) derived from the free end of the other one of the resistors is applied to the virtual ground input of an operational amplifier formed by a common emitter stage (Q4) coupled to an emitter follower (Q5). The operational amplifier has a capacitive (C1) feedback between its output and virtual ground input so that the d.c. potential at said input has no effect on the d.c. operating point of the output.As an alternative, resistive (Rf) feedback may be used instead of the capacitive feedback.Another embodiment (FIG. 2) enables the input and output voltage swings to be increased without unduly degrading the bandwidth.

摘要： N.sup.2 acoustic wave devices (A,B,S,T; where N is an integer greater than unity) with substantially the same electrical impedance and transfer characteristics at a given operating frequency are electrically connected in a parallel-series arrangement which has substantially the same electrical impedance and transfer characteristics as any one of the individual N.sup.2 devices, but an increased active device area. The increased active area reduces stress and alleviates acoustically-induced migration in the metal of, for example, transducer electrode fingers (6,7) of resonators at high power levels. The parallel-series arrangement consists of N groups, each of which comprises N devices (A,B or S,T), the corresponding pairs of terminals (4,54 and 54,55) of which are connected in series. Some terminals (54 or 55) may be common to two or more devices and some devices may have merged transducers in which the electrode fingers (6 or 7) of one transducer are a longitudinal extension of the fingers of a parallel transducer. In the case of multi-port devices the input and output terminal pairs may be differently grouped as regards the individual devices to which they belong.
