LTC5505-1/LTC5505-2
ELECTRICAL CHARACTERISTICS The q denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. VCC = 3.6V, SHDN = VCC = HI, SHDN = 0V = LO, RF Input Signal is Off,
unless otherwise noted.

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