1、Model 599 Technical Description With the Model 599 Eagle, Ten-Tec has created a transceiver combining simplified controls and ease of operation with the excellent performance of a low first IF 160- through 6-meter ham-band architecture in a compact, mobile-friendly structure. The analog portion of t

2、he radio is double conversion with IF frequencies of 9.0015 MHz and 22.5 kHz. A third conversion to zero-frequency IF is accomplished in the DSP processor. General coverage receive is provided between 0.5 and 30 MHz. Refer to the Block Diagram for the following discussion. Receive signals are routed

3、 through the optional antenna tuner and transmit lowpass filter to a switchable 10dB attenuator at the input of the BPF/Preselector board. This board also contains the bandpass filter selected for the band in use and a switchable 12dB receive preamplifier. On the TX/RX board, output from the preampl

4、ifier is mixed with the first Local Oscillator to 9.0015 MHz and routed optionally through the noise blanker to one of three roofing filters. After selectivity roofing, IF amplification is provided by a variable gain amplifier which also develops the high-level AGC. Finally, the 9.0015 IF signal is

5、mixed with the second LO to develop a 22.5 kHz low IF for the Signal Processing Unit (SPU). Based on a 36.096 MHz temperature-stable reference, the Synthesizer board generates first and second LOs via fractional-N synthesis and fixed frequency division. The SPU samples the low IF at 96K samples per

6、second and applies the resulting data to a digital signal processor. Numerical algorithms running in the digital processor accomplish additional selectivity filtering, low-level AGC, and demodulation. The resulting audio appears at the speaker and line outputs. The PIC processor in the CPU module ex

7、ecutes firmware stored in EEPROM to perform housekeeping functions such as synthesizer programming/tuning, signal switching, and front panel display and control input. Based on the control inputs from the front panel (or remotely via the USB interface), the CPU writes display information, tunes the

8、LOs, adjusts selectivity, and chooses both receiver detection and transmit emission modes. Transmit operation is basically the reverse of receive. Audio or CW signals are generated at zero-frequency (baseband) in the DSP, frequency-shifted to the 22.5 kHz low IF, and output to mixers on the TX/RX bo

9、ard for conversion to the operating frequency. The signal then travels in the reverse direction through the selected Bandpass Filter to the low-level drivers and Power Amplifier, then finally through the Lowpass Filter and optional antenna tuner to the antenna. If the tuner is installed, forward and

10、 reverse power measurements from the SWR bridge are used by the CPU to select the correct inductance and capacitance in an L-network to provide a 50 Ohm load to the transmitter output.
