Note 1:
Stresses beyond those listed under Absolute Maximum Ratings between PIN = –40dBm and 0dBm for 3600MHz, 5800MHz). The dynamic may cause permanent damage to the device. Exposure to any Absolute range is defined as the range of input power over which the linearity error Maximum Rating condition for extended periods may affect device is within ±1dB. reliability and lifetime.
Note 6:
Input A to Output B (Channel A to Channel B) isolation is defined
Note 2:
The LTC5583 is guaranteed functional over the temperature range as the ratio of input power levels at the two channels when the interfering from –40°C to 85°C. channel (Channel A with higher power) results in a 1dB output deviation
Note 3:
Logarithmic Intercept is an extrapolated input power level from the in the interfered channel (Channel B with lower power) and vice versa. best-fit log-linear straight line, where the output voltage is 0V. Sweep one channel input power level while holding the other channel input
Note 4:
Operation over a wider frequency range is possible with reduced at –45dBm for 450MHz, 880MHz, 2140MHz, 2700MHz, 3600MHz, and at performance. Consult the factory for information and assistance. –35dBm for 5800MHz.
Note 5:
Linearity error is the difference in dB between the actual output
Note 7:
For frequency separation = 0Hz between the two input signals, and the best-fit straight line at 25°C (using linear regression between channel-to-channel isolation is a function of the phase difference between P these two signals. The worst-case isolation is assumed. IN = –50dBm and 0dBm for 450MHz, 880MHz, 2140MHz, 2700MHz; 5583fa 5
