General Description
The BC2401 is a single chip OOK (On-Off keyed) RF
receiver.
The device will convert this RF input into a digital
output signal, making it a genuine RF-in to Data-
out integrated device and providing an easy to use
solution for UHF receiver implementation. With
few external components and low-current power
consumption features, it provides an ideal solution
for low cost and power-sensitive applications, such
as found in the automotive and consumer application
area. The device contains a low-noise amplifier, a
regenerative circuit, an integrated quench circuit
and baseband data-recovery circuitry. The device
is available in an 8-pin SOP-EP package type and
specified for an extended temperature range of -40°C
to +85°C.
