manufacturer: description:the input signal at pin data produces amplitude shift key (ask) modulation of the vco output. this is achieved by oncoff keying of the bias current in the output power amplifier stage. the output of the pa is a balanced output (pin out and outb) and is current source driven (open collector outputs). the outputs of which should be d.c. referenced to a positive supply voltage (anticipated to be vcc in most applications). the current source outputs can drive a pcb antenna directly (figure 6) or if a higher output power is required on limited supply headroom via a simple impedance transforming net- work. a balanced output stage is used as it automatically suppresses the even order harmonics of the fundamental. in order to obtain the benefits of this output stage it is essential to use a balanced antenna. |
