hi,
im currently doing my a project right now and it's dealing with microwave frequencies. I NEED A POWER AMPLIFIER that will boost my output and the same time has a frequency response from 900Mhz to 2.5Ghz. is there an IC that will do the job??
i've searched the internet but i haven't found one yet..
please help me..
tnx
Such amplifiers are common as dirt and some are even available through Digikey. Of course, I'm assuming you don't need a lot of power. Once your needs exceed about 15 dBm or so, your selection is reduced somewhat. Below 10 dBm there are many many to choose from. Try searching at companies like Anadigics, Avago Technologies (former Agilent semi), NXP Semiconductor (former Philips semi), RF Monolithics, NEC Semiconductor (via CEL), RF Microdevices, Mimix Broadband, M/ACom, Toshiba, Freescale, Texas Instruments, National Semiconductor, Infineon, Atmel, IBM, Maxim, Renesas, Rohm, ST Microelectronics, Analog Devices, and many more. I suspect I haven't even listed half of them.
But the key question is how much power do you want? There is a sudden drop in the number of suppliers as soon as you exceed about 15 dBm. It is much more difficult to find a single IC that does the job covering 900 MHz to 2.5 GHz when your power requirement exceeds about 33 dBm.
Many of these manufacturers are having such a good time selling to cellphone makers that they don't bother with small volumes through distribution and so some of these will be unavailable to the amateur or hobbyist. Deal with distributors to insure supply.
I did a search at Richardson Electronics (an RF specialist distributor) and found this high power product that might work for you:
AETHERCOMM SSPA 0.8-2.5-20 (and others in Aethercomm lineup)
Here is an example of a broadband amp in IC form that is puts out about 24 dBm : Anadigics AGB3301.
This might also be useful if you only need about 1 watt:
