Product Description
The AG606 is a dual amplifier containing two internal
matched amplifiers optimal for a push-pull configuration.
The internal amplifiers employ InGaP HBT technology
for a cost-effective low-distortion solution.

The AG606 is ideal for drop amplifiers, splitters, and
other low to moderate power outside plant CATV
applications. The amplifier can also be useful in low
power headend applications such as linear laser drivers.

The AG606 has excellent VSWR when used in a 75 :
push-pull configuration. It is provided in a low-cost
environmentally-friendly lead-free/green/RoHS-compliant
SOT-89 package.

1. Test conditions unless otherwise noted: T = 25ºC, 800 MHz on each individual single-branch
amplifier in a 50a1 test fixture using a +7V supply and a 20.5 a1 dropping resistor.
2. 3OIP measured with two tones at an output power of +5 dBm/tone separated by 1 MHz. The
suppression on the largest IM3 product is used to calculate the 3OIP using a 2:1 rule.
3. Typical parameters reflect performance in a push-pull application circuit.
4. Balun, board, and connector losses have not been extracted, but typically account of 0.4 dB loss
midband and 1.1 dB loss at 860 MHz.
5. Measured at +34 dBmV/channel, 79 channels Flat Loading.
6. OIP2 is measured at f1 + f2 at 5 dBm / tone.
