(see am transmitter data sheet) these modules show a very high frequency stability over a wide operating temperature even when subjected to mechanical vibrations or manual handling. a unique laser trimming process which has been patented gives a very accurate on board inductor, removing the need for any adjustable components. all receivers are compatible, producing a cmos/ttl output, and require connections to power and antenna only. the hrr6 is a version with very low current consumption which has a typical quiescent current drain of only 0.5ma. in addition the hrr8 opreates from a 3vdc supply. block diagram r.f. pre-amp r r .f. oscillator a.f. amplifier low pass filter comp - arator quench oscillator rf gnd v v r r f f af gnd test point rf gnd o o / / p p v v a a f f
