It is called transmitreceive switch (TR switch). It protects the receiver from damages caused by high power transmitter. It also provides the received echo signal to the receiver without connecting it to the transmitter. 2.11.8 Functions of the Transmitter · Generates high power at high frequencies. · Switches on and off to produce pulses of RF energy with the specified direction. · Sends the pulses at regularly Thus we notice that the transponder is a miniaturized microwave receiveramplifiertransmitter unit, having an extremely low weight and low power consumption. 11.5 TRANSMITTER BLOCK DIAGRAM OF EARTH STATION A typical microwave channel is assumed to contain.about 1000 audio channels. In this scheme, to save bandwidth so that more audio channels can be earth transmitting station is shown in Fig. 11.3. Ch1 Ch2 ChN . . . Mixer IF amplifier RF oscillator Power amp A Quick Review To quickly review all that has been covered to this point, I will follow an RF signal through the general transmitter and receiver block diagrams introduced in Figures 32 and 31, repeated here for convenience. Transmitter Block Diagram Figure 322 Transmitter block diagram. Receiver Block Diagram Figure 323 Receiver block diagram. Review Transmitter signal is injected, which is already carrying the information to. Starting with the transmitter in Figure 322, Figure 2.20 is a block diagram of an FHSS transmitter.and receiver. Both transmitter and receiver local oscillator frequencies are controlled by frequency synthesizers. The receiver must detect the beginning of a transmission and synchronize its synthesizer to that of the transmitter. When the receiver knows the pseudorandom pattern of the transmitter, it can lock onto the incoming signal and must then remain in synchronization by changing frequencies at the same time as the receiver block diagram, and the lower portion corresponds to the transmitter. The duplexer and the synthesizer local oscillator (LO) operating at the ultrahigh frequency (UHF) band are shared by both the receiver and the transmitter. The duplexer consists of two bandpass filters with a common input port and.two output ports. One filter is centered at receiver frequency band. It is used as the receiver preselection filter and to suppress transmission power leaking to the receiver.

The goal is usually to send information from one OFDMA also allows subchannelization, or grouping of subcarriers, in both uplink and downlink, which provides frequency diversity. 1.7 WiMAX Transceiver Figure 1.5 shows a WiMAX transmitter and receiver block diagram. In the transmitter, the serialtoparallel converted data is mapped in the modulator. As a centerpiece of the WiMAX transmitter, the inverse.fast Fourier transform (IFFT) (FFT in the receiver) realizes the time domain WiMAX signal by modulating each data symbol onto Receiver • Receiver sensitivity • Losses in cable and connectors 1.6.1 Transmitter Data Modulator Amplifier 1.6.2 Receiver Filter FIGURE 1.1 Transmitter block diagram.
