MAX2067 19-4080 Rev 0 4/08 50MHz to 1000MHz High-Linearity, Serial/Analog-Controlled VGA General Description Features The MAX2067 high-linearity analog variable-gain ampli- 50MHz to 1000MHz RF Frequency Range fier (VGA) is a monolithic SiGe BiCMOS attenuator and Pin-Compatible Family Includes amplifier designed to interface with 50 systems oper- ating in the 50MHz to 1000MHz frequency range (see MAX2065 (Analog/Digital VGA) the Typical Application Circuit). The analog attenuator MAX2066 (Digital VGA) is controlled using an external voltage or through the SPI-compatible interface using an on-chip 8-bit DAC. +21.9dB (typ) Maximum Gain Because each stage has its own RF input and RF out- 0.5dB Gain Flatness Over 100MHz Bandwidth put, this component can be configured to either opti- mize NF (amplifier configured first), or OIP3 (amplifier 31dB Gain Range last). The devices performance features include 22dB Built-In DAC for Analog Attenuation Control amplifier gain (amplifier only), 4dB NF at maximum gain (includes attenuator insertion loss), and a high OIP3 Excellent Linearity (Configured with Amplifier level of +43dBm. Each of these features makes the Last) MAX2067 an ideal VGA for numerous receiver and +43dBm OIP3 transmitter applications. +66dBm OIP2 In addition, the MAX2067 operates from a single +5V supply with full performance, or a single +3.3V supply +19dBm Output 1dB Compression Point with slightly reduced performance, and has an -70dBc HD2 adjustable bias to trade current consumption for linearity -87dBc HD3 performance. This device is available in a compact 40- pin thin QFN package (6mm x 6mm) with an exposed 4dB Typical Noise Figure (NF) pad. Electrical performance is guaranteed over the Single +5V Supply (Optional +3.3V Operation) extended temperature range (T = -40C to +85C).

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.
