8. Fine Adjustment of the Oscillator Frequency
To set the frequency of the oscillator exact to 11.15 MHz, the frequency is adjustable in 8 steps, by adding 3 different internal capacities
the frequency could be reduced.

= +25°C, VRF = VAF = RFOVB = 3.6V, all bits set to “0”, unless otherwise specified. Test circuit, see
The tx conversion gain of the RF transmitter is somehow dependent on temperature. This is determined by the fundamental
principle of this circuitry. Means have been taken inside the limiter amplifier, being in the signal path before MODIN, which are
able to completely compensate this temperature behavior.
