Note 1:
Absolute Maximum Ratings are those values beyond which the life
Note 5:
RF performance is tested at: of a device may be impaired. 1800MHz, 14dBm, –14dBm (LTC5505-1)
Note 2:
Specifications over the –40°C to 85°C operating temperature 1800MHz, 12dBm, –14dBm (LTC5505-2) range are assured by design, characterization and correlation with
Note 6:
For input RF power levels >16dBm, VCC minimum is 3V and an RF statistical process controls. input series resistor of 20Ω is required to limit the input current.
Note 3:
The rise time at VOUT is measured between 0.5V and 1.5V.
Note 7:
Guaranteed by design.
Note 4:
Bandwidth is calculated using the 10% to 90% rise time equation: BW = 0.35/rise time. 5505f 3
