Micro transceiver assembly

Abstract

The invention discloses a micro transceiver assembly. The micro transceiver assembly comprises an AGC (automatic gain control) receiving module and an ALC (adaptive logic circuit) emitting module, wherein the AGC receiving module comprises a first balance amplifier, a first micro belt filter, a first electrically controlled attenuator, a second balance amplifier, a first coupler and a first direct-current processing circuit; the ALG emitting module comprises a second electrically controlled attenuator, a third balance amplifier, a second micro belt filter, a fourth balance amplifier, a second coupler and a second direct-current processing circuit; the first balance amplifier, the second balance amplifier, the third balance amplifier, the fourth balance amplifier, the first micro belt filter, the second micro belt filter, the first electrically controlled attenuator, the second electrically controlled attenuator, the first coupler and the second coupler are manufactured on a ceramic base plate through a superfine micro belt film process. The micro transceiver assembly is integrated on a circuit in the form of a distribution parameter, so that peripheral assemblies are reduced, the integration degree of the whole transceiver assembly is relatively high and the size of the transceiver is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a miniaturized transceiver assembly. Background technique [0002] When the receiver receives a signal, the signal level at its input may vary in a wide range, and the output power of the receiver varies with the size of the external signal, so the output of the receiver will have a very different strength. signal power. If it is necessary to maintain the linear amplification of the receiving equipment in such a wide range without saturation and distortion of the signal, it is necessary to control the gain of the receiver to keep the output signal at an appropriate level to ensure the normal operation of the receiver. And through an AGC (Automatic Gain Control, automatic gain control) circuit, the gain of the amplifying circuit can be automatically adjusted according to the signal strength. The AGC circuit adjusts the output signal using an effective combination of...
