miniADSB Technical Data
Vcc recommended = 3.5 - 4V DC (abs. min. 3V; abs. max. 5V)
Icc = see graphics below
Input: Z=50 Ohms, min: ca. -90 dBm; max. -12 dBm*
*may not be relevant for intermittent signals
Output: 0.68 - 2.1 V, max. 400 ľA
ANT min: minimum detectable signal level at antenna input, considering a broadband noise of -97 dBm/1090 MHz/50 MHz
before Logamp at ANT min: signal level at AD8313 input when ANT min is present
ANT at PO1DB: signal level at antenna input, when the last LNA reaches Po(1dB)
ANT at POSAT: signal level at antenna input, when the last LNA reaches saturation
before last SAW at PO1dB: signal level at last SAW input when last LNA reaches Po(1db). Shall not exceed 10 dBm.
Dynamic: total dynamic range of frontend
Note miniADSB maximum input
power level at the antenna may be limited to -12.3 dBm (approx. 100m
distance from antenna, cont. signal)
Graphics: miniADSB current consumption
Note: recommended Vcc for best SNR and stability = 3.5V - 4V
Graphics: miniADSB transfer function
Note: AD8313 saturation level = 0dBm, abs. max input level = 25 dBm; theoretical min antenna input level = -90.1 dBm for 50 MHz BW/1090 MHz
