Since the inverting input exhibits a 500Ω input imped-

ance, terminate the input with a 56Ω resistor when the

device is configured for an inverting gain in 50Ω appli-

c a tions (te rmina te with 88Ω in 75Ω a p p lic a tions ).

Terminate the input with a 49.9Ω resistor in the nonin-

widths. These buffers use internal 500Ω resistors to

provide a preset closed-loop gain of +2V/V in the non-

inverting configuration or -1V/V in the inverting configu-

ration. Excellent harmonic distortion and differential

gain/phase performance make these buffers an ideal

choice for a wide variety of video and RF signal-pro-

cessing applications.

ensures low output impedance, which reduces gain

sensitivity to load variations. This feedback also pro-

duces demand-driven current bias to the output tran-

sistors for ±120mA drive capability, while constraining

total supply current to less than 7mA.

La yo u t Te c h n iq u e s

Maxim recommends using microstrip and stripline tech-

niques to obtain full bandwidth. To ensure that the PC

board does not degrade the buffer’s performance, design

it for a frequency greater than 1GHz. Pay careful attention

to inputs and outputs to avoid large parasitic capaci-

tance. Whether or not you use a constant-impedance

board, observe the following guidelines when designing

the board:

±5.5V. For single-supply operation, bypass the V pin

to ground with a 0.1µF capacitor as close to the pin as

possible. If operating with dual supplies, bypass each

supply with a 0.1µF capacitor.

• Use surface-mount instead of through-hole compon-

ents for better high-frequency performance.

• Use a PC board with at least two layers; it should be

as free from voids as possible.
