[0005] It should be added that if each transistor is only provided with a gate electrode 993 with a length of 1 μm between its drain electrode 991 and source electrode 992, the P1dB of the radio frequency switch unit 94 will only be about 20~30dBm, so , will not be applicable to most digital wireless communication systems due to specification restrictions
[0006] In addition, since the above-mentioned conduction path 810 must pass through at least six gate electrodes with a length of 1 μm, in order to meet the condition of impedance matching, six equivalent resistors (not shown in the figure) must also be added. Will greatly increase the area of the radio frequency switch unit 94

The invention relates to a digital wireless communication transceiver module which is respectively connected with a fundamental frequency module and a radio frequency antenna module in a coupled mode. The digital wireless communication transceiver module comprises a transmitting unit, a receiving unit, a power amplifying unit and a radio frequency switch unit. Due to the fact that the length of a gate electrode of each transistor in the radio frequency switch unit is increased to be more than 1 micrometer, the compression point of the radio frequency unit per decibel is effectively improved.
