manufacturer:linear description:the amplifier is a class a amplifier, which is linearized by the effective high-frequency emitter degeneration contributed by the bond wire inductance. the last stage has an open collector, and an external load is therefore necessary. the dc current in the amplifier is adjusted with an external bias resistor. the ratio of the output current (the current flowing in the load and output transistor) to the current in the bias resistor is about 28. the maximum output current is about 15 ma, which gives a maximum bias current of 535ua. a 2.7kω bias resistor will give approximately this bias current. the components between the antenna and the output of the power amplifier are for impedance matching. the impedance matching circuit will depend on the type of antenna used. the power amplifier is turned on internally after the control word is clocked into the shift register. this changes the vco load and influences the pll. the pa should be switched on and off externally by the microcontroller to prevent spurious components from being transmitted before the pll stabilises. |
