The RX5003 hybrid receiver is ideal for short-range wireless control and data applications where
robust operation, small size, low power consumption and low cost are required. The RX5003
employs RFM’s amplifier-sequenced hybrid (ASH) architecture to achieve this unique blend of
characteristics. All critical RF functions are contained in the hybrid, simplifying and speeding de-
sign-in. The RX5003 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 receiver out-
of-band rejection. The RX5003 generates virtually no RF emissions, facilitating compliance with
FCC Part 15 and similar regulations.
