For my application, I need Pout = 7 Watts in the 400 to 460 MHz band. My nominal supply voltage is 12 VDC. But, the supply voltage can drop as low as 8 VDC (RF power can drop 2 dB at 8 VDC). Does NXP have any data on the MRF1518 at 8 VDC? The data sheet shows power and efficiency down to 9 VDC (figures 8 & 9). My application is also very PCB space limited and must be very low cost. If I went with the MRF1517 then I would have to add a DC-DC converter to the PCB which adds cost and consumes PCB area. Thank you in advance.
