ACA1205 750/870 MHz CATV Line Amplifier Data Sheet - Rev 2.1 FEATURES • 15 dB Gain • Very Low Distortion • Excellent Input/Output Match • Low DC Power Consumption • Good RF Stability with High VSWR Load Conditions • Surface Mount Package Compatible with Automatic Assembly • Low Cost • Repeatability of Monolithic Fabrication • Meets Cenelec Standard • RoHS-Compliant Package Option S7 Package 16 Pin Wide Body SOIC with Heat Slug APPLICATIONS • • CATV Distribution Amplifier High Linearity CATV Amplifier PRODUCT DESCRIPTION The ACA1205 is a surface mount monolithic GaAs RF Linear Amplifier that has been developed to replace, in new designs, the standard CATV Hybrid amplifiers currently in use. The MMIC consist of two RF Input parallel amplifiers, each with 15 dB gain. The amplifier is optimized for exceptionally low distortion and noise figure while providing flat gain and excellent input and output return loss. 15dB 12dB 15dB 12dB ACA1205 ACA0861B Figure 1: Hybrid Application Diagram 02/2005 RF Output ACA1205 1 GND GND 16 2 N/C VA 15 3 RFINA RFOUTA 14 4 GND GND 13 5 GND GND 12 6 RFINB RFOUTB 11 7 IADJ VB 10 8 GND GND 9 Figure 2: Pin Out Table 1: Pin Description 2 PIN NAME DESCRIPTION PIN NAME DESCRIPTION 1 GND Ground 9 GND Ground 2 N/C No Connection 10 VB Supply for Amplifier B 3 RFINA Input to Amplifier A 11 RFOUTB Output from Amplifier B 4 GND Ground 12 GND Ground 5 GND Ground 13 GND Ground 6 RFINB Input to Amplifier B 14 RFOUTA Output from Amplifier A 7 IADJ Current Adjust 15 VA Supply for Amplifier A 8 GND Ground 16 GND Ground Data Sheet - Rev 2.1 02/2005 ACA1205 ELECTRICAL CHARACTERISTICS Table 2: Absolute Minimum and Maximum Ratings PARAMETER MIN MAX UNIT Amplifier Supplies (pins 10, 11, 14, 15) 0 +15 VD C RF Input Power (pins 3, 6) - +70 dBmV -65 +150 °C Soldering Temperature - +260 °C Soldering Time - 5.0 se c Storage Temperature Stresses in excess of the absolute ratings may cause permanent damage. Functional operation is not implied under these conditions. Exposure to absolute ratings for extended periods of time may adversely affect reliability. Notes: 1. Pins 3 and 6 should be AC-coupled. No external DC bias should be applied. 2. Pin 7 should be pulled to ground through resistor R1, as shown in Figure 3. No external DC bias should be applied.
