A transceiver includes a power control circuit in the transmitter that operates on a packet-by-packet basis. The transceiver can, for each packet, set a variable gain amplifier to a first gain and use predetermined gain increments to thereafter increase gain until a gain hold event. The gain hold event can be an expiration of a time duration allocated for changing gain or a desired power being reached, whichever event occurs first. The gain can be adjusted by a predetermined amount based on an operating condition.

The invention claimed is: 1. A method of transmitting packets, the method comprising: determining whether an output power of a power amplifier reaches a desired power when transmitting a packet; increasing a gain of a variable gain amplifier (VGA) by a predetermined increment when the output power does not reach the desired power; repeating determining and increasing the gain until a gain hold event, the gain hold event being first of a time duration allocated for changing gain expiring and the desired power being reached, wherein the VGA uses a gain associated with the gain hold event to transmit a remainder of the packet. 2. The method of transmitting packets of claim 1, wherein for each subsequent packet being transmitted, further including: setting the VGA to the gain associated with the gain hold event of a last transmitted packet; and repeating determining and increasing the gain until another gain hold event. 3. The method of transmitting packets of claim 1, wherein for each subsequent packet being transmitted, further including: setting the VGA to the gain associated with the gain hold event of a last transmitted packet minus a predetermined gain; and repeating determining and increasing the gain until another gain hold event. 4. The method of transmitting packets of claim 3, wherein the predetermined gain is user-configurable. 5. The method of transmitting packets of claim 3, wherein the predetermined gain varies based on an operating condition. 6. The method of transmitting packets of claim 1, wherein for each subsequent packet being transmitted, further including: setting the VGA to the gain associated with the gain hold event of a last transmitted packet minus a predetermined number of increments; and repeating determining and increasing the gain until another gain hold event. 7. The method of transmitting packets of claim 1, further including: setting the VGA to an initial gain value. 8. A method of transmitting packets, the method comprising: for an initial packet, setting a variable gain amplifier (VGA) to an initial gain and using predetermined gain increments to thereafter increase gain until a gain hold event; and for subsequent packets, setting the VGA to a gain associated with the gain hold event of a last transmitted packet and using the predetermined gain increments to thereafter increase gain until the gain hold event, wherein the gain hold event is one of a time duration allocated for changing gain expiring and a desired power being reached, whichever occurs first. 9. The method of transmitting packets of claim 8, wherein for subsequent packets, further including: setting the VGA to the gain associated with the gain hold event of a last transmitted packet minus a predetermined gain based on an operating condition. 10. The method of transmitting packets of claim 8, wherein for subsequent packets, further including: setting the VGA to the gain associated with the gain hold event of a last transmitted packet minus a predetermined number of increments based on an operating condition. 11. A method of transmitting packets, the method comprising: for each packet, setting a variable gain amplifier (VGA) to a first gain and using predetermined gain increments to thereafter increase gain until a gain hold event, wherein the gain hold event is one of a time duration allocated for changing gain expiring and a desired power being reached, whichever occurs first. 12. The method of transmitting packets of claim 11, wherein the first gain is an initial gain. 13. The method of transmitting packets of claim 11, wherein the first gain is a gain associated with the gain hold event of a last transmitted packet. 14. The method of transmitting packets of claim 11, further including: setting the VGA to the gain associated with the gain hold event of a last transmitted packet minus a predetermined gain based on an operating condition. 15. The method of transmitting packets of claim 11, further including: setting the VGA to the gain associated with the gain hold event of a last transmitted packet minus a predetermined number of increments based on an operating condition. 16. A method of transmitting packets, the method comprising: on a packet-by-packet basis, setting a variable gain amplifier (VGA) to a first gain and using predetermined gain increments to thereafter increase gain until a gain hold event, wherein the gain hold event is one of a time duration allocated for changing gain expiring and a desired power being reached. 17. The method of transmitting packets of claim 16, further including: setting the VGA to the gain associated with the gain hold event of a last transmitted packet minus a predetermined gain based on an operating condition. 18. The method of transmitting packets of claim 16, further including: setting the VGA to the gain associated with the gain hold event of a last transmitted packet minus a predetermined number of increments based on an operating condition.
