RX5500
433.92 MHz
Hybrid
Receiver
The RX5500 hybrid receiver is ideal for short-range wireless control applications where robust
operation, small size, low power consumption and low cost are required. The RX5500 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 RX5500 is sensitive and stable. A wide dynamic range log detector provides robust perfor-
mance in the presence of on-channel interference or noise. Two stages of SAW filtering provide
excellent receiver out-of-band rejection. The RX5500 generates virtually no RF emissions, facili-
tating compliance with ETSI I-ETS 300 220 and similar regulations.
