ATF-36077
2–18 GHz Ultra Low Noise Pseudomorphic HEMT
Data Sheet
Description
AvagoTechnologies' ATF-36077 is an ultra-low-noise Pseudo-
morphic High Electron Mobility Transistor (PHEMT), pack-
aged in a low parasitic, surface-mountable ceramic package.
Properly matched, this transistor will provide typical 12
GHz noise figures of 0.5 dB, or typical 4 GHz noise figures
of 0.3 dB. Additionally, the ATF-36077 has very low noise
resistance, reducing the sensitivity of noise performance to
variations in input impedance match, making the design of
broadband low noise amplifiers much easier. The premium
sensitivity of the ATF-36077 makes this device the ideal
choice for use in the first stage of extremely low noise
cascades. The repeatable performance and consistency
make it appropriate for use in Ku-band Direct Broad-cast
Satellite (DBS) Television systems, C-band Television Receive
Only (TVRO) LNAs, or other low noise amplifiers operating
in the 2-18 GHz frequency range.

Note:
1. The F
min
values at 2,4, and 6 GHz have been adjusted to reflect expected circuit losses that
will be encountered when matching to the optimum reflection coefficient (Γ
opt
) at these
frequencies. The theoretical F
min
values for these frequencies are: 0.10 dB at 2 GHz, 0.20 dB
at 4 GHz, and 0.29 dB at 6 GHz. Noise parameters are derived from associated s parameters,
packaged device measurements at 12 GHz, and die level measurements from 6 to 18 GHz.
