Hello together, can someone help me to interpret the specifications in a technical data sheet?
The FET´s data sheet specifies two performances. In the case of the MRF6S21140HS it shows:
Typical 2 - carrier W - CDMA Performance: VDD = 28 volts, IDQ = 1200 mA,
1.: Pout = 30 Watts Avg., F = 2112.5 MHz, Channel Bandwidth = 3.84 MHz,
2.: Capable of handling 10: 1 VSWR, @ 28 Vdc, 2140 MHz, 140 Watts CW Output power
Does this mean now that you can load at a bandwidth of 3.84 MHz only with 30 watts (may), in narrowband operation like CW probably 140 watts.
How is it with DATV? Is it possible to load more than 30 watts with a correspondingly lower bandwidth (for example 500 kb/s)?
Is the maximum load between narrowband and 3.84 MHz bandwidth linear, from 140 watts down to 30 watts?
What can I accept?
