    The bandwidth gain product is 65m, and the magnification is as needed.

    The chip manual provides typical amplification circuits and related component parameters without the need for inventions.

    The unit gain bandwidth of the chip is 500MHz, which cannot complete the task of 20x40=800MHz bandwidth gain product.

    5V power supply, 100 load, the output voltage swing is G>10 when the bandwidth gain product is 300M, G=10 times the bandwidth can reach 10M, the circuit diagram is on PDF, but pay attention to impedance matching in high-frequency applications, when the positive and negative power supply is powered, it is best to connect a 104 between the positive and negative power supply

    Op amps with a unit gain bandwidth of more than 200MHz include EL5202, EL5204, EL8403, EL8202, EL8302, EL5932, EL5178, EL5378 (the above are Intersil products), THS7530, THS4501, THS4001, THS4221, THS4021, THS3001, OPA691, OPA695, OPA657, OPA846, OPA2677, OPA2691, OPA690, OPA2690, OPA2652, OPA685 (the above are TI products), and the highest bandwidth I know are THS3001 (6500MHz) and THS3202 (9000MHz), all of which are TI products.

    OPA690 can be used, its bandwidth is sufficient, 1800MHz, its working voltage single power supply can go to +12V, if the amplification is about 17 times, it can work to about 100MHz.

    The OP07 is no, and its typical unit gain bandwidth is 600kHz, which is far worse than 5MHz.

    HA2510 is also not good, although the bandwidth index is better than OP07 (30MHz), according to its bandwidth calculation, the signal of 5MHz can only be amplified by about 6 times, and it is not enough to amplify about 17 times.

    What kind of task can be accomplished by an op amp must be based on the index parameters, and it cannot be taken for granted that it can or cannot be assumed.

    A hundred times magnification can be cascaded with two op amps, so that there is no need for such a large bandwidth gain product. OPA843 (low distortion), OPA842 (low distortion), OPA690 are all sufficient, as well as AD8009 (1G bandwidth gain product) and OPA820 (low noise). These are my usual op amps.

    Op amps with a unit gain bandwidth of around 450MHz or higher than 450MHz are EL8102, EL8202, EL8302, EL8203, EL5205, EL5375, EL5364, EL5392, EL5204, EL8403, EL5178, EL5378, OPA690, OPA657, OPA846, OPA695, OPA691, OPA2652, OPA2677, OPA2691, THS3202, SN10501, SN10503, THS7530, THS4501, etc.
