5 / 8 page 400MHz to 2500MHz SiGe Ultra-Low-Noise Amplifiers _______________________________________________________________________________________ 5 Detailed Description The MAX2640 and MAX2641 are ultra-low-noise ampli- fiers that operate with RF input frequency ranges of 400MHz to 1500MHz (MAX2640) or 1400MHz to 2500MHz (MAX2641). These devices are available in SOT23-6 packages and contain internal bias circuitry to minimize the number of required external components. Their small size and low external component count make them ideal for applications where board space is limited. Applications Information External Matching Components The MAX2640/MAX2641 are easy to use, generally requiring only five external components as shown in the Typical Operating Circuit. To reduce external compo- nent count further, replace external inductors with microstrip transmission lines. The high reverse isolation allows the tuning of the input matching network without affecting the output match, and vice versa. Select input and output matching networks to obtain the desired combination of gain, noise figure, and return loss per- formance. The Typical Operating Circuits show the rec- ommended input and output matching networks for the MAX2640/MAX2641 at 900MHz and 1900MHz, respectively. These values are optimized for best simultaneous gain, noise figure, and return loss perfor- mance. To aid in the design of matching networks for other frequencies, Tables 1 and 2 list typical device S- parameters and Tables 3 and 4 list typical device noise parameters. NAME FUNCTION 1 RFIN Amplifier Input. AC-couple to this pin with a DC blocking capacitor. Use recommended input matching network (see Typical Operating Circuit). 2, 3, 5 GND Ground. For optimum performance, provide a low inductance connection to the ground plane. PIN 4 RFOUT Amplifier Output. Use the recommended series blocking or matching capacitor (see Typical Operating Circuit). 6 VCC Supply Voltage. Bypass to ground directly at the supply pin. The value of the bypass capacitor is deter- mined by the lowest operating frequency. Additional bypassing may be necessary for long VCC lines (see Typical Operating Circuit). Pin Description |
