A transceiver (100) includes a radio frequency power amplifier (116) which is biased by an active bias circuit (110). Active bias circuit (110) provides a low cost bias circuit for amplifier (116) which adjusts the bias over changes in temperature and supply voltage levels to provide a constant output power. A set of control inputs (122-126) coming from controller (108) provide for power output level adjustement for the amplifier (116) in a frequency modulated (FM) environment and for both power and modulation level adjustments in an amplitude modulated (AM) environment.

Un émetteur-récepteur (100) comporte un amplificateur de puissance radioélectrique (116) qui est polarisé par un circuit de polarisation actif (110). Ce circuit de polarisation actif (110), qui constitue un circuit peu onéreux pour un amplificateur (116), ajuste la polarisation selon les changements de température et les niveaux de tension d'alimentation pour produire une puissance de sortie constante. Un ensemble d'entrées de commande (122-126) provenant d'un régisseur (108) permet l'ajustement du niveau de puissance pour l'amplificateur (116) dans un environnement modulé en fréquence (F.M.), et les ajustements de niveau de puissance et de modulation dans un environnement modulé en amplitude (A.M.).
