A81-3 amplifier basic information:

Commonly used packaging methods are TO-8, 4 PIN

A81-3 amplifier core information:

The minimum operating temperature of the A81-3 is -54 °C and the maximum operating temperature is 85 °C.

In addition, its maximum voltage standing wave ratio is 1.3 (voltage standing wave ratio (VSWR) refers to the ratio of the standing wave antinode voltage to the node voltage amplitude, also known as the standing wave coefficient and standing wave ratio. VSWR is 1.25 :1, the reflected power is 1.14%; when VSWR is 1.5, the reflected power is 4.06%; when VSWR is 1.75, the reflected power is 7.53%) The maximum slew rate of A81-3 given by the manufacturer is 31 mA.A81-3 amplifier Gain can reach: 15.5 dB (Amplifier gain is the logarithm of the ratio of amplifier output power to input power, used to express the degree of power amplification. It also refers to the amplification factor of voltage or current. Similarly, decibel is the unit of amplifier gain.) Its maximum The operating frequency is: 500 MHz, and the minimum operating frequency is: 20 MHz. The corresponding maximum input power is 10 dBm. When a single-ended signal is added to the transmission line, the single-ended impedance felt by the signal on the A81-3 is 50 Ω. (The characteristic impedance of A81-3 is 50 Ω)

The range of its power supply is: 15 V.

Relevant dimensions of A81-3:

A81-3 has 4 terminals.

A81-3 amplifier additional information:

A81-3 is not Rohs certified. It contains lead. A81-3 packaging materials are mostly METAL.
