... ISM Band Systems • Wireless Local Loop Systems Product Description The RF2504 is an integrated oscillator and buffer ampli- fier chain designed to achieve extremely low sensitivity to fluctuations in load impedance and power supply noise, thereby greatly reducing load pulling and pushing. The IC offers great flexibility, yet is easy to use ...

... The specified output power is measured into a 50 load. The IC has a high output impedance, and if desired, output matching can be used to obtain more power by transforming 50 On the RF2504, this could be accomplished by simply changing the values of the external output inductor and capacitor. Preliminary into a higher impedance. ...
