RF Input Frequency Range LTC4401-1 (Note 6) 300 2700 MHz LTC4401-2 (Note 6) 300 2000 MHz RF Input Power Range RF Frequency = 900MHz (Note 6) –28 18 dBm (LTC4401-1) RF Frequency = 1800MHz (Note 6) –26 18 dBm RF Frequency = 2400MHz (Note 6) –24 16 dBm RF Frequency = 2700MHz (Note 6) –22 16 dBm RF Input Power Range RF Frequency = 900MHz (Note 6) –28 18 dBm (LTC4401-2) RF Frequency = 2000MHz (Note 6) –26 18 dBm RF Input Resistance Referenced to VCC ● 150 250 350 Ω
Note 1:
Absolute Maximum Ratings are those values beyond which the life
Note 5:
This is the time from SHDN rising edge 50% switch point to of a device may be impaired. VPCA = 0.25V.
Note 2:
The LTC4401-X is guaranteed to meet performance specifications
Note 6:
Guaranteed by design. This parameter is not production tested. from 0°C to 70°C. Specifications over the – 30°C to 85°C operating
Note 7:
Includes maximum DAC offset voltage and maximum control temperature range are assured by design, characterization and correlation voltage. with statistical process controls.
Note 8:
Bandwidth is calculated using the 10% to 90% rise time:
Note 3:
Slew rate is measured open loop. The slew time at VPCA/B is BW = 0.35/rise time measured between 1V and 2V.
Note 9:
Measured 12µs after SHDN = HI.
Note 4:
Maximum DAC zero-scale offset voltage that can be applied to PCTL.
