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/RoHS­compliant 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.

9 V 59 ohms 2010
10 V 74 ohms 2010
12 V 102 ohms 2512

The proper value for R1 is dependent upon the supply
voltage and allows for bias stability over temperature.
