Connection to reception line
The reception line is connected through 1.5pF capacitance to antenna as following
Figure 7.15
. This configuration
impedance is not 50Ω because the transmission character is prioritized over the reception character. LAPIS technology
tests the circuit with this impedance on the mass production process and confirm the minimum reception sensitivity is
-97dBm (BER<0.1%, Center frequency 2450MHz, GFSK100kbps, fdev=50kHz). If the addition of reception line
causes the reduction of transmission power, increase the inductance of the matching circuit.
