wide band driver amp from 400MHz to 2400 MHz

can someone recommend me a driver amp from 400 to 2400 MHz , with output power about 24 dBm or 22 dBm , with Max supply of 5 V . and 3 V will be better

thanks in advance

how to calculate electrical degrees(lenghts of PCBs) at frequencies not given at datasheet? is there a simple software for this task?

TX Line from AWR:

also agilent Lincalc is very good

I know how to calculate the lenght of a 50 ohm microstrip with having its electrical degress.(txLine and other software do this)

But how can I calculate the value of electrical degress at a frequency of interest?

for ex:

EL3 for SXA-389

13.2 degree at 850MHZ
28.7 degree at 1960MHZ
35.9 degree at 2450MHZ
(see page 6 of datasheet)

what is it at 1600MHZ for example?

what software can be used for this purpose(a simple and free one)?

lincalc and TXline can be used ,
give them the lenght , and they will give the degress

I must have one of them( lenght or degree at a FREQ)at start.

How can I calculate one of both(how to find degree or lenght at start)?

I know after having one of them I can convert it to another one by txLine ,AppCAD ,....


please read me question carefully.

The Electrical Wavelength (in meters) is:
EW = C/[f*SQRT(Er)]
where C = 300, f is in MHz and Er is the Dielectric Constant of the board.

The Electrical Length (in degrees) is:
EL = (360*PL)/EW
where PL is the Physical Length of the line in meters.
