February 17, 2005[Ideas For Design] 40.680-MHz FSK RF Transmitter Uses Two CMOS Inverters
Single-chip transmitters proposed by some IC manufacturers have good electrical performance, but they're often plagued by some drawbacks. For instance, they're hard to find in small quantities. Also, they become obsolete too fast. And, they rarely have a second source. For frequencies lower than 50 MHz, RF power of 10 mW, and a maximum frequency-shift-keying (FSK) data rate of 2 kbits/s, the circuit shown in the figure can be an attractive solution. The IC used is the...
