Product Description

The EC1019 is a general-purpose buffer amplifier that

offers high dynamic range in a low-cost surface-mount

package. At 1000 MHz, the EC1019 typically provides 20

dB of gain, +34 dBm Output IP3, and +19 dBm P1dB.

The EC1019 consists of Darlington pair amplifiers using

the high reliability InGaP/GaAs HBT process technology

and only requires DC-blocking capacitors, a bias resistor,

and an inductive RF choke for operation. The device is

ideal for wireless applications and is available in low-cost,

surface-mountable plastic SOT-86 and SOT-89 packages.

The EC1019 is also available in a lead-free/green/RoHS-

compliant SOT-89 package. All devices are 100% RF and

DC tested.

The broadband MMIC amplifier can be directly applied to

various current and next generation wireless technologies

such as GPRS, GSM, CDMA, and W-CDMA. In addition,

the EC1019 will work for other various applications within

the DC to 4 GHz frequency range such as CATV and fixed

wireless.

2. 3OIP measured with two tones at an output power of +4 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. Large-signal gain is tested with an input power level of +4 dBm.
