EVALUATION KIT AVAILABLE MAX2664/MAX2665 VHF/UHF Low-Noise Amplifiers General Description The MAX2664 and MAX2665 are ultra-compact LNAs for VHF/UHF applications. These devices incorporate a broadband LNA with an integrated bypass switch. The MAX2664 covers the UHF frequency range from 470MHz to 860MHz, and the MAX2665 covers the VHF frequency range from 75MHz to 230MHz. Features The MAX2664 and MAX2665 are available in a 4-bump (0.8mm x 0.8mm x 0.64mm), lead-free, wafer-level package (WLP). ●● UHF and VHF Frequency Range • MAX2664: 470MHz to 860MHz • MAX2665: 75MHz to 230MHz ●● Low Noise Figure • MAX2664: 1.2dB • MAX2665: 1.1dB ●● High Gain: 15dB ●● Zero-Power Bypass Mode ●● Single +2.4V to +3.5V Supply Voltage ●● Low Current: 3.3mA ●● Small Footprint: 0.8mm x 0.8mm ●● Thin Profile: 0.64mm Applications Ordering Information Each device has a zero-power bypass mode for improved high-signal-level handling conditions. Additionally, the output port is internally matched to 50Ω while a single external inductor is used to match the input port to 50Ω. ●● ●● ●● ●● Smartphones/Handsets MP3 Players Home Audio/Video Portable Navigation Devices TEMP RANGE PIN-PACKAGE MAX2664EWS+ PART -40ºC to +85ºC 4 WLP MAX2665EWS+ -40ºC to +85ºC 4 WLP +Denotes a lead(Pb)-free/RoHS-compliant package.

Connect to the PCB ground plane with minimal trace inductance. A2 VCC Supply Voltage. Bypass to ground with a 1000pF capacitor as close as possible to the IC. B1 RFIN RF Input. Requires an external matching inductor and DC-blocking capacitor. The nominal internal DC voltage is 750mV. B2 RFOUT/CTRL Detailed Description FUNCTION RF Output and Bypass Control (see the Applications Information section). RFOUT is internally matched to 50Ω and incorporates an internal DC-blocking capacitor. The MAX2664/MAX2665 are low-power LNAs designed for VHF/UHF applications. The devices feature an internal LNA bypass control mode for better linearity under highinput-signal power conditions. The devices are offered in a small WLP package. www.maximintegrated.com Input and Output Matching Only an inductor in series with a DC-blocking capacitor is needed to form the input-matching network. The Typical Application Circuit shows the recommended inputmatching network. These values are optimized for the best simultaneous gain, noise figure, and return loss performance. Tables 1 and 2 list typical device S-parameter values. The devices integrate an on-chip 50Ω outputmatching network, eliminating the need for external matching components.

Active Bypass Mode Control The devices’ RFOUT/CTRL pin is used to control the bypass mode of the LNA. When set to logic-high through an external 1kΩ resistor, the devices’ active mode is enabled. Conversely, when connected to logic-low, the devices’ bypass mode is enabled. An external DC-blocking capacitor should be used to isolate the control function of this dual-purpose pin (see the Typical Application Circuit). Applications Information A properly designed PCB is essential to any RF microwave circuit. Use controlled-impedance lines on all highfrequency inputs and outputs. Bypass VCC with decoupling capacitors located close to the device. For long VCC lines, it might be necessary to add additional decoupling capacitors. Locate these additional capacitors further away from the device package. Proper grounding of the GND pin is essential. If the PCB uses a topside RF ground, connect it directly to the GND pin. For a board where the ground is not on the component layer, connect the GND pin to the board with multiple vias close to the package.
