Page 7: Theory Of Operation
Philips Semiconductors Product specification Wide-band high-frequency amplifier NE/SA/SE5205A THEORY OF OPERATION where R =12Ω, V =0.8V, I =5mA and I =7mA (currents rated at V =6V). The design is based on the use of multiple feedback loops to provide wide-band gain together with good noise figure and terminal Under the above conditions, V is approximately equal to 1V. -
