we are using PA device for 350-510 MHz application with 2W o/p.
we have used suggested Reference design as per data sheet.
it is getting tuned to 300-400 MHz . also we observed that when it is tested from 410 Mhz on wards the o/p falls and current reduces from 300 mA to 180 & still low up to 100mA at 500 MHz.
pl suggest how to go about. in future we would be needing bulk nos to be used.
