Notes for PCB layout:
1. The RF output pin must match to a 50 Ω strip-line or coplanar waveguide on the BTM510 (no antenna).
2. Ensure there are no exposed conductors under the module to avoid shorts to the module test points.
3. The PCB footprint is provided for guidance only. Users may wish to modify the PCB land dimensions to suit
their specific manufacturing or process.
2.5 Audio Design Requirements
The audio inputs of the BTM510/511 can operate in either line input mode or microphone mode. The input
circuit has a two stage amplifier – the first stage provides a fixed 24 dB gain and the second a variable gain of
between -3 dB and 18 dB. If an input gain of less than 24 dB is selected, then the first stage is switched out and
the module is operating in line input mode. The BTM511 can support both Single-Ended and Fully Differential
Stereo Line Input (Figure 3).
