RF Synthesizer 4MHz – 8GHz with output level up to +27dBm

Wideband frequency synthesizer (RF signal generator) with output frequency range from 4 MHz to 8 GHz, high frequency resolution and high output signal level. Output power is variable and AGC controlled with digital compensation system based on calibration data written in memory of the device. Synthesizer also has multi-path filtering block for additional harmonic suppression. Device is digitally controlled via SPI interface. Frequency tuning can be dynamically programmed within all specified frequency range. High output signal level allows the device to be used as a Local Oscillator (heterodyne) for passive balance mixers when more than +13 dBm required for linearity of the path. It also can be used for nonlinear distortion parameters measure of high-power output stages: one-decibel compression point – P_1dB and intermodulation intercept point IP₃ (with aid of two synthesizers for

RF Out

Output Frequency

Output frequency is given by the following equation

F_out=(M/N)·F_ref ,

where F_ref — reference oscillator frequency (int. 147 MHz), N — integer in range from 0 to 2⁴⁸ (provided that F_out is in range given by the table below), M — constant integer given by the following table for each appropriate frequncy range.
