The AMIS-52000 is a dual receiver and a transmitter in a
single device. Data is transmitted at data rates up to
19.6Kbps. The AMIS-52000 can be used in half-duplex
mode, or simplex mode. Control is provided by an external
microprocessor. Power output adjust, frequency trim, filter
bandwidth selection, antenna or receiver diversity selection
and crystal divider values can be changed to compensate
for device tolerances. The transmit section of the AMIS-
52000 generates the output carrier signal when the TX/RX
pin is toggled to enable the RF carrier. RF output power is
controlled by setting register TXPOWER (0x02) to some
value, setting a DC voltage level on the pin RFPWR (0x00 is
the lowest setting and 0xFF is the highest setting). The
receive section of the AMIS-52000 is configured to accept
the input signals from either or both of the two antennas.
The detected signals are summed inside the receiver,
providing the received digital signal output. The receiver
operates as a very low IF superheterodyne receiver with
internal filtering.
8.0 Functional Design Description
AMIS-52000 Block Diagram
This section shows a typical design with external
components for 433.92MHz operation. The following
sections will describe each external circuit.
RX1, RX2, RF Input Impedance
There are two identical RF input circuits (AMIS-52000 pins
RX1 and RX2). The LNA for these inputs requires a DC
voltage path to ground. The following circuit diagram
shows a suggested circuit for 433.92MHz.
