Figure 3 shows a conceptualblock diagramof an enhanced FM receiverarchitectureused to support a short embedded antenna. The “tuned resonance” is implemented using an on-chip tunable varactor and tuning algorithm. The design utilizes a mixed-signal, digital, low-IF architecture with a digital ...
Increasingly, in order to provide enhanced services, along with improved spectral efficiency and coverage, the design of these radios has moved from traditional analog-based modulation schemes—such as FM and PM—to digital modulation approaches. Receivers for these radios must be capable of ...

Base stations may also implement the feedback mode transmit diversity (FMTD) algorithm, which is a power control/beam forming application that uses multiple antenna transmissions with varying weights. Again, the computation is multiply-accumulate intensive, similarly to the rake receiver. For such app...
The block diagram of a typical PLL FM demodulator circuit is shown below. The values of the gain parameters chosen for the loop filter control the loop bandwidth of the PLL. The size of the loop bandwidth determines the range of error signal frequencies that the loop filter will pass. The ...

2. Using the handshaking process to implement synchronization to ensure that the receiver is properly flushed and ready to receive a complete frame without error before the modules may exchange data. Figure 5 shows the data flow for handshake. There are two ping loops for the daisy-chain ...
Use a proper antenna on the receiver side, which is capable of covering the 1090 MHz band, such as an ADS-B Double 1/2 Wave Mobile Antenna9; using a poorly tuned or poorly made antenna will result in a lack of range for your air radar. ...
