LT5537EDDB#TRMPBF

LT5537 is a wide dynamic range RF/IF detector, operational from below 10MHz to 1000MHz. The lower limit of the operating frequency range can be extended to near DC by the use of an external capacitor. The input dynamic range at 200MHz with ±3dB nonlinearity is 90dB (from –76dBm to 14dBm, single-ended 50 ohm input). It is widely used in applications such as linear-to-log signal level conversion, received signal strength indication (RSSI), RF power control, RF/IF power detection, receiver RF/IF gain control, envelope detection, ASK receiver etc.

• Sensitivity -76dBm or better at 200MHz
• Log-linear transfer slope of 20.3mV/dB typical at (R1 = 33K, VCC = 3V, ENBL = 3V, TA = 25°C)
• Supply voltage range is 2.7V to 5.25V
• Supply current is 13.5mA at 3V
• Shutdown current is 500µA typical (ENBL = low, VCC = 3V, ENBL = 3V, TA = 25°C)
• Temperature coefficient is -0.007dB/°C typical at (f = 10MHz, PIN = -20dB)
• Operating ambient temperature is -40°C to 85°C
• Package style is 8-lead plastic DFN
