RF MATCHING NETWORK

An RF matching network is available to match the LNA input
impedance and PA output with the 50 Ω SMA connector (J4)
for ADuCRF101 at different frequencies depending on the
board used.
Different boards are available based on the RF transceiver
frequency required. See Table 4 for the relevant model numbers.

The list of components for the different models available is
available in Table 8 to Table 12.
The 868 MHz/915 MHz models come with a matching network
for differential PA only. The matching network components can
be modified to evaluate the single-ended PA. The list of compo-
nents for single-ended PA operating at 868 MHz/915 MHz is
available in Table 13.
The 433 MHz models come preloaded with a combined matching
network for both differential and single ended PA operation.

SENSITIVITY MEASUREMENTS

To perform the BER test on the RF transceiver, the internal
clock and data signals of the transceiver can be brought to the
ADuCRF101 GPIO pins
•
The CLOCK signal can be brought out to P0.6.
•
The DATA signal can be brought out to P2.6.
