Frequently Asked Questions
What gain does MAX2650EUS+ deliver, and over which frequency range is that gain specified?
MAX2650EUS+ provides 16.5 dB of gain across its operating frequency range of 800 MHz to 1000 MHz. This makes it well-suited for cellular 850 MHz band receivers and 900 MHz ISM-band systems where a single-stage amplifier must recover weak signals before further processing.
How does the 50 ohm characteristic impedance of MAX2650EUS+ simplify RF PCB layout?
MAX2650EUS+ is designed for a 50 ohm system impedance, matching the standard impedance of coaxial connectors, transmission lines, and most RF ICs. This eliminates the need for external matching networks in many designs, reducing BOM and PCB trace complexity, and ensuring predictable gain flatness across the 800 MHz to 1000 MHz band.
What maximum input power can MAX2650EUS+ handle before compression, and why is that important in receive chains?
MAX2650EUS+ is rated for a maximum CW input power of 13 dBm before reaching its compression point. In receiver front ends where strong out-of-band interferers can appear at the antenna, this 13 dBm headroom protects downstream mixer and ADC stages from overload, reducing the need for additional input limiting or filtering.
