Transmission Characteristics
Unless otherwise noted, limits printed in BOLD characters are guaranteed for V
+70˚C by correlation with 100% electrical testing at T
Transmit and receive gains programmed for maximum 0 dBm0 test levels (0 dB Gain). All other limits are assured by correla-
tion with other production tests and/or product design and characterization. All signals referenced to GND. Typicals specified at
