Agilent Technologies supplies:
RF and IF components in the block down-converter (LNB)
Detects and amplifiers incoming signal
[10.9 - 12.7 GHz, 0.3-0.6 dB NF; 10-15 dB gain nominal]
ATF-36077
amplifiers incoming signal
[10.9 -12.7 GHz, 0.3-1.2 dB NF; 10-15 dB gain nominal]
ATF-36163
converts signal from 12 GHz to 1 GHz
active mixer:
ATF-36163
diode mixers:
HSMS-8202
amplifiers IF signal
[900-2000 MHz, 30 dB gain nominal, 5 dBm Pout nominal]
preferred ICs: INA-51063 + INA-54063
other IC options: INA-03184, INA-10386, INA-52063, MSA-0886
discrete transistor options: AT-415
Some systems include multiple IFs for multi-channel outputs
These systems may make use of a switch function
HSMP-389x
These systems may also use a detector diode
HSMS-2815
provides signal for downconversion
[10 GHz low side or 13 GHz high side, 0 dBm nominal Pout]
AT-310 , AT-320 bipolar transistors for best phase noise
ATF-13786, ATF-26886 FETs
