| 1. A radio frequency (RF) integrated circuit comprising:
a substrate;
a set of one or more analog subcircuits on the substrate; and
a programmable bias current supply on the substrate coupled to the subcircuit set to provide bias currents to the analog subcircuits,
including providing programmable bias current to each of one or more analog subcircuits forming a first subset of the set,
such that one or more characteristics of the RF integrated circuit are modifiable by programming the programmable bias supply,
wherein the integrated circuit is for operation as a radio transceiver including a receiver and a transmitter,
wherein the subcircuit subset includes a power amplifier in the transmitter, and
wherein the programmable bias supply is to set the bias of the power amplifier to achieve different power consumption and
performance.
