MAX2630-MAX2633中文资料

_______________General DescriptionThe MAX2630/MAX2631/MAX2632/MAX2633 are low-voltage, low-noise amplifiers for use from VHF to microwave frequencies. Operating from a single +2.7V to +5.5V supply, these devices have a flat gain response to 900MHz. Their low noise figure and low supply current make them ideal for receive, buffer, and transmit IF applications.The MAX2630/MAX2631 are biased internally, eliminat-ing the need for external bias resistors or inductors. The MAX2632/MAX2633 have a user-selectable supply cur-rent, which can be adjusted by adding a single external resistor. This allows customized output power and gain according to specific applications requirements. The MAX2631/MAX2633 feature a shutdown pin that allows them to be powered down to less than 1µA supply cur-rent. Aside from a single bias resistor required for the MAX2632/MAX2633, the only external components needed for this family of amplifiers are input and output blocking capacitors and a V CC bypass capacitor.The MAX2630 comes in a 4-pin SOT143 package, re-quiring minimal board space. The MAX2631/MAX2632come in small 5-pin SOT23 packages. The MAX2633comes in a 6-pin SOT23 package.________________________ApplicationsPersonal Communicating Systems Cordless Phones Global Positioning Systems Cellular Phones Wireless Local Area Networks ISM Radios Wireless Local Loops TV Tuners Land Mobile RadiosSet-Top Boxes____________________________Featureso Single +2.7V to +5.5V Operation o Internally Biased (MAX2630/MAX2631)o Adjustable Bias (MAX2632/MAX2633)o 6.6mA Supply Current (insensitive to supply voltage)o 1µA Shutdown Current (MAX2631/MAX2633)o 3.7dB Noise Figure o 13.4dB Gaino Ultra-Small SOT PackagesMAX2630–MAX2633VHF-to-Microwave, +3V ,General-Purpose Amplifiers________________________________________________________________Maxim Integrated Products1_________________Pin Configurations__________Typical Operating Circuit______________Ordering Information19-1181; Rev 1; 7/97*The first two letters in the SOT top mark identify the part,while the remaining two letters are the lot-tracking code.For free samples & the latest literature: , or phone 1-800-998-8800.For small orders, phone 408-737-7600 ext. 3468.M A X 2630–M A X 2633VHF-to-Microwave, +3V ,General-Purpose Amplifiers 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICS(V CC = +3V, Z 0= 50Ω, f IN = 900MHz, R BIAS = 10k Ω(MAX2632/MAX2633), V SHDN = V CC (MAX2631/MAX2633), T A = +25°C, unless otherwise noted.)Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

Their small size and internal bias circuitry make them ideal for applications where board space is limited. The MAX2632/MAX2633have a user-selectable bias current that allows the user to set both gain and output power for a particular appli-cation, and the MAX2631/MAX2633 incorporate shut-down capability.__________Applications InformationExternal ComponentsThe MAX2630–MAX2633 are easy to use, as shown in the Typical Operating Circuit and Figures 1, 2 and 3. Input and output series capacitors may be necessary to block DC bias voltages generated by the amplifiers from inter-acting with adjacent circuitry. These capacitors must be large enough to contribute negligible reactance in a 50Ωsystem at the minimum operating frequency. Use the fol-lowing equation to calculate their minimum value:where f (in megahertz) is the minimum operating frequency.The V CC pin must be RF bypassed for correct opera-tion. To accomplish this, connect a capacitor between the V CC pin and ground, as close to the package as is practical. Use the same equation given above (for DC-blocking capacitor values) to calculate the minimum capacitor value. If the PC board has long V CC lines,additional bypassing may be necessary. This can be done farther away from the package, if needed.Proper grounding of the GND pin is essential. If the PC board uses a topside RF ground, connect it directly to the GND pin. For a board where the ground plane is not on the component side, the best technique is to con-nect the GND pin to it with a plated through-hole close to the package.An on-chip buffer at the MAX2631/MAX2633’s SHDN pin makes bypassing this pin unnecessary except in very noisy applications. When RF filtering is needed,use a bypass capacitor similar to the one used on V CC .Since negligible current flows into this pin, additional RF filtering may be done with a series resistor.To set the MAX2632/MAX2633’s supply current,connect a resistor from the BIAS pin to ground. To estimate the value of this resistor, refer to the graph Supply Current vs. R BIAS in the Typical Operating Characteristics .C BLOCK =53,000f(pF)M A X 2630–M A X 2633VHF-to-Microwave, +3V ,General-Purpose Amplifiers 8_______________________________________________________________________________________Figure 4.

max263翻译

Max263（264）是开关电容有源滤波器设计用于精密滤波应用。

中心频率，Q，工作模式都可以通过输入引脚选择。

Max263不需要用外部元件去实现带通，低通，高通，全通滤波。

max263是专门带通应用程序和包含一个通用运算放大器。

两个第二阶滤波器部分都包含在这两个设备。

通过fclk/f0Max263和267的中心频率可以到达57KHZ，而max264和268可以到达140KHZ。

Max263（264）有28个引脚，max267（268）有24个引脚。

1、滤波器设计软件化2、中心频率32阶可控3、Q值128阶可控4、Q值与f0独立可编程5、f0可达140KHz6、支持＋5V和士5V两种供电方式芯片诸引脚功能如下（括号内数字为引脚号）：V+(10):供电正极, 并接旁路电容尽量靠近该脚V-(18):供电负极, 并接旁路电容尽量靠近该脚GND(19):模拟地CLKA(13):A单元元时钟输人, 该时钟在芯片内部被二分频CLKB(14):B单元时钟输人, 该时钟在芯片内部被二分频OSC OUT(20):连至晶体, 组成晶振电路(若接时钟信号时, 该脚不连)INA,INB(5,1):滤波器输人BPA,BPB(3,27): 带通输出LPA,LPB(2,28):低通输出HPA,HPB(4,26):高通、带陷、全通输出M0,M1(8,7):模式选择,+5V高，-5V低F0-F4(24,17,23,12,11):时钟与中心频率比值(FCLK/f0)编程端Q0-Q6(15,16,21,22,25,6,9):Q编程端。

1、供给电压士15V2、输入电压士0.3V3、输入电流士50Ma对M0、M1两个管脚编程可使芯片工作于模式1、2、3、4几种方式,对应的功能如表1所示。

时钟与中心频率比值与编码对应如表2所示。

模式1:当我们要实现全极点低通或带通滤波器如切比雪夫、巴特沃斯滤波器时这种模式是很有用的, 有时该模式也用来实现带陷滤波器, 但由于相关零极点位置固定, 使得用作带陷时受到限制。
