The TR7003 hybrid transceiver is ideal for short-range wireless data applications where robust

operation, small size, low power consumption and low cost are required. The TR7003 employs

RFM’s amplifier-sequenced hybrid (ASH) architecture to achieve this unique blend of character-

istics. All critical RF functions are contained in the hybrid, simplifying and speeding design-in.

The receiver section of the TR7003 is sensitive and stable. A wide dynamic range log detector,

in combination with digital AGC and a compound data slicer, provide robust performance in the

presence of on-channel interference or noise. Two stages of SAW filtering provide excellent re-

ceiver out-of-band rejection. The transmitter includes provisions for both on-off keyed (OOK) and

amplitude-shift keyed (ASK) modulation. The transmitter employs SAW filtering to suppress out-

put harmonics, facilitating compliance with FCC and similar regulations.
