The MAX2640/MAX2641 are low-cost, ultra-low-noise amplifiers designed for applications in the cellular, PCS, GPS, and 2.4GHz ISM frequency bands. Operating from a single +2.7V to +5.5V supply, these devices consume only 3.5mA of current while providing a low noise figure, high gain, high input IP3, and an operating frequency range that extends from 300MHz to 2500MHz.

The MAX2640 is optimized for 300MHz to 1500MHz applications, with a typical performance of 15.1dB gain, input IP3 of -10dBm, and a noise figure of 0.9dB at 900MHz. The MAX2641 is optimized for 1400MHz to 2500MHz applications, with a typical performance of 14.4dB gain, an input IP3 of -4dBm, and a noise figure of 1.3dB at 1900MHz.

These devices are internally biased, eliminating the need for external bias resistors and chokes. In a typical application, the only external components needed are a two-element input match, input and output blocking capacitors, and a VCC bypass capacitor.

The MAX2640/MAX2641 are designed on a high-frequency, low-noise, advanced silicon-germanium process and are offered in the space-saving 6-pin SOT23 package.

Applications

  • 400MHz/900MHz/2.4GHz ISM-Band Radios
  • Cellular/PCS Handsets
  • Cordless Phones
  • GPS Receivers
  • Wireless Data
  • Wireless Local Area Networks (WLANs)

  • All Critical Peripheral Components Included

Product Detail

The MAX2640/MAX2641 evaluation kits (EV kits) simplify the evaluation of the MAX2640/MAX2641 low-noise amplifiers (LNAs). They enable testing of the device's RF performance and require no additional support circuitry. The signal inputs and outputs use SMA connectors to facilitate the connection of RF test equipment.

The MAX2640 EV kits are assembled with the MAX2640 and incorporate input and output matching components optimized for an RF frequency of 900MHz. The MAX2641 EV kits are assembled with the MAX2641 and incorporate input and output matching components optimized for an RF frequency of 1900MHz. All matching components may be changed to match RF frequencies from 400MHz to 1500MHz for the MAX2640 and from 1400MHz to 2500MHz for the MAX2641. Consult Tables 1 through 4 in the MAX2640/MAX2641 data sheet for devices S-parameters and noise parameters for the design of matching networks at other frequencies.

Applications

  • 400MHz/900MHz/2.4GHz ISM-Band Radios
  • Cellular and PCS Mobile Phones
  • Cordless Phones
  • GPS Receivers
  • Wireless Data
  • Wireless Local Area Networks (WLANs)
