NTENNA SWITCHING CIRCUIT The antenna switching circuit functions as a low pass filter while receiving However its impedance becomes very high while D9 and D10 are turned ON Thus transmit signals are blocked from entering the receiver circuits The antenna switching circuit employs a type diode switching system Received signals are passed through the low pass filter L1 L2 C3 C5 C6 The filtered signals are applied to the type antenna switching circuit D9 D10 The passed signals are then applied to the RF amplifier cir cuit 4 1 2 RF CIRCUIT The RF circuit amplifies signals within the range of frequen cy coverage and filters out of band signals The signals from the antenna switching circuit are amplified at the RF amplifier Q15 after passing through the tunable bandpass filter D12 L21 C104 C105 The amplified sig nals are applied to the 1st mixer circuit Q19 after out of band signals are suppressed at the 3 stages tunable band pass filter D13 L22 C111 C113 D14 L23 C116 C117 D15 L24 C120 C122 Varactor diodes are employed at the bandpass filters that track the filters and are controlled by the CPU IC7 via the D A convertor IC9 using 1 4 signals These diodes tune the centre frequency of an RF passband for wide bandwidth receiving and good image response rejection 4 1 3 1ST MIXER AND 1ST IF CIRCUITS The 1st mixer circuit converts the received signal into a fixed frequency of the 1
