ULN OP AMP SMD under $3

[mafio]

I want the perfect op. Any suggestions.

What does this mean?

Well the Impossible: high gain, flat gain, wideband, low cost, low power, etc

(Not sure if there is a way to create a net chart in a forum or just chatter to the wall.)

Practically I am looking for the following in the order of importance. (if there is something blaringly wrong with the follow characteristics shout it out when you know the answer)

Ultra Low Noise best possible
gain: 20db and flat against a wideband
band: 4 GHz would be happy with 2 Ghz
power: Under a watt simple IC
Cost: Under $3 for a purchase of 1000
Trusted Name brand

 Simple suggestions no need to blow this topic up.

Are you sure you want an op-amp, or do you want a MMIC?  Further, does it have to go down to DC?

20 dB from an opamp up to 2 ghz implies a gain-bandwidth product of 200 GHz.
You can get various fixed-gain amplifiers with a high input impedance, e.g. http://www.ti.com/product/ths4302, or you can get 50 ohm input MMIC (also fixed-gain) like the well-known Minicircuits parts or similar things from Analog (Hittite), RFMD, NXP, etc.

I forgot about MMIC due to their lower frequency negligence. Just wish it was cheaper. Thanks.

Still don't mind other suggestions.
