Page 7: Theory Of Operation
Philips Semiconductors Wide-band high-frequency amplifier THEORY OF OPERATION The design is based on the use of multiple feedback loops to provide wide-band gain together with good noise figure and terminal impedance matches. Referring to the circuit schematic in Figure 17, the gain is set primarily by the equation: which is series-shunt feedback. -

Page 10: Output Power
One must be careful, however, not to select too low levels because the test equipment may not be able to recover the signal from the noise. For the SA5205A we have chosen an output level of -10.5dBm with fundamental frequencies of 100.000 and 100.01MHz, respectively. - Page 11 Philips Semiconductors Wide-band high-frequency amplifier = 25 = 6V = 75 = 50 FREQUENCY—MHz a.
