19-5476; Rev 0; 8/10 TION KIT EVALUA BLE IL AVA A VHF/UHF Low-Noise Amplifiers 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. Each device has a zero-power bypass mode for improved high-signal-level handling conditions. Additionally, the output port is internally matched to 50I while a single external inductor is used to match the input port to 50I. The MAX2664 and MAX2665 are available in a 4-bump (0.8mm x 0.8mm x 0.64mm), lead-free, wafer-level package (WLP).

Requires an external matching inductor and DC-blocking capacitor. The nominal internal DC voltage is 750mV. B2 RFOUT/CTRL RF Output and Bypass Control (see the Applications Information section). RFOUT is internally matched to 50I and incorporates an internal DC-blocking capacitor. Detailed Description 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 high-input-signal power conditions. The devices are offered in a small WLP package. 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 input-matching network. These values are optimized for the best simultaneous gain, noise figure, and return loss performance. Table 1 lists typical device S-parameter values. The devices integrate an on-chip 50I outputmatching network, eliminating the need for external matching components. 9 MAX2664/MAX2665 Bump Configuration MAX2664/MAX2665 VHF/UHF Low-Noise Amplifiers Table 1.

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 1kI resistor, the devices’ active mode is enabled. Conversely, when connected to logic-low, the devices’ bypass mode is disabled. 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 high-frequency 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. Table 5.
