The digital attenuator is 20.5dB (typ) Maximum Gain controlled as a slave peripheral using either the SPI- compatible interface or a parallel bus with 31dB total 0.4dB Gain Flatness Over 100MHz Bandwidth adjustment range in 1dB steps. An added feature 31dB Gain Range allows rapid-fire gain selection between each of four Supports Four Rapid-Fire Preprogrammed steps, preprogrammed by the user through the SPI- Attenuator States compatible interface. The 2-pin control allows the user Quickly Access Any One of Four Customized to quickly access any one of four customized attenua- Attenuation States Without Reprogramming tion states without reprogramming the SPI bus. the SPI Bus Because each stage has its own RF input and RF output, Ideal for Fast-Attack, High-Level Blocker Protection this component can be configured to either optimize NF Prevents ADC Overdrive Condition (amplifier configured first), or OIP3 (amplifier last). The devices performance features include 22dB amplifier Excellent Linearity (Configured with Amplifier gain (amplifier only), 5.2dB NF at maximum gain (includes Last) attenuator insertion loss), and a high OIP3 level of +42.4dBm OIP3 +42.4dBm. Each of these features makes the MAX2066 +65dBm OIP2 an ideal VGA for numerous receiver and transmitter +19dBm Output 1dB Compression Point applications. -68dBc HD2 -88dBc HD3 In addition, the MAX2066 operates from a single +5V supply with full performance, or a single +3.3V supply 5.2dB Typical Noise Figure (NF) with slightly reduced performance, and has an Fast, 25ns Digital Switching adjustable bias to trade current consumption for linearity Very Low Digital VGA Amplitude Overshoot/ performance. This device is available in a compact 40- Undershoot pin thin QFN package (6mm x 6mm) with an exposed pad.

This formula can be used when the temperature of the exposed J C JC CC CC pad is known while the device is soldered down to a printed-circuit board (PCB). See the Applications Information section for details. The junction temperature must not exceed +150C. Note 2: Junction temperature T = T + ( x V x I ). This formula can be used when the ambient temperature of the PCB is J A JA CC CC known. The junction temperature must not exceed +150C. Note 3: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a 4-layer board. For detailed information on package thermal considerations, refer to www.maxim-ic.com/thermal-tutorial. Note 4: T is the temperature on the exposed pad of the package. T is the ambient temperature of the device and PCB. C A Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. +3.3V SUPPLY DC ELECTRICAL CHARACTERISTICS (Typical Application Circuit, high-current (HC) mode, V = V = +3.0V to +3.6V, T = -40C to +85C.
