Input / Output Matching
The RF input / output is differential (
RF_N
and
RF_P
). In addition there is supply
switch output pin (
TXRX_SWITCH
) that
must have an external DC path to
RF_N
and
RF_P
.
In RX mode the
TXRX_SWITCH
pin is at
ground and will bias the LNA. In TX mode
the
TXRX_SWITCH
pin is at supply rail
voltage and will properly bias the internal
PA.
The RF output and DC bias can be done
using different topologies. Some are
shown in Figure 3 and Figure 4.
Component values are given in Table 2.
Using a differential antenna, no balun is
required.
If a single ended output is required (for a
single ended connector or a single ended
antenna), a balun should be used for
optimum performance. The balun can be
realized using discrete inductors and
capacitors, or a LTCC balun can be used.
Transmitter Test Modes
The
EM2420
can be set into different
transmit test modes for performance
evaluation. The test mode descriptions in
the following sections require that the chip
is first reset, the crystal oscillator is
enabled using the
SXOSCON
command
strobe and that the crystal oscillator has
stabilized.
Unmodulated carrier
An
transmitted
MDMCTRL1.TX_MODE
to 2, writing 0x1800
to the
DACTST
register and issue a
STXON
command strobe. The transmitter
is then enabled while the transmitter I/Q
DACs are overridden to static values. An
unmodulated
carrier
by
may
be
setting
unmodulated carrier will then be available
on the RF output pins.
A plot of the single carrier output spectrum
from the
EM2420
is shown in Figure 29
below.
