700MHz to 2700MHz Analog VGA with Threshold

Alarm Circuit and Error Amplifier for Level Control

Typical Operating Characteristics (continued)

(Typical Application Circuit with analog attenuator set to minimum attenuation, VCC = 4.75V to 5.8V, fRF = -16dBm, TC = -40°C to

+95°C, and RF ports are connected to 50Ω sources and loads, unless otherwise noted. Typical values are at TC = +25°C, VCC = 5.5V,

PRF = -16dBm, CTRL1 = 1, CTRL2 = 0, VPLVLSET = 2.5V, unless otherwise noted.)
