Claim 0:
1. Wireless circuitry comprising:
at least one digital-to-analog converter having an input and an output that is coupled to an antenna; and
a quadratic phase generator having
an output port coupled to the input of the at least one digital-to-analog converter,
a first integrator stage having an input and an output,
a second integrator stage having an input coupled to the output of the first integrator stage and having an output connected to the output port, and
a switch having a first input configured to receive a first value that is a function of a chirp count q that defines a number of chirps at the output port, a second input configured to receive a second value different than the first value, and an output that is coupled to the input of the first integrator stage.
