CHA7010
RoHS COMPLIANT
X-band GaInP HBT High Power Amplifier
GaAs Monolithic Microwave IC Description
The CHA7010 is a monolithic two-stage GaAs high power amplifier designed for X band applications. This device is manufactured using a GaInP HBT process, including, via holes through the substrate and air bridges. A nitride layer protects the transistors and the passive components. Special heat removal techniques are implemented to guarantee high reliability. To simplify the assembly process: * the backside of the chip is both RF and DC grounded * bond pads and back side are gold plated for compatibility with eutectic die attach method and thermosonic or thermocompression bonding process.

Assembly recommendations
CHA7010
For thermal and electrical considerations, the chip should be brazed on a metal base plate. The RF, DC and modulation port inter-connections should be done according to the following table: Port IN (24) OUT (12) Vc (5, 10, 14, 19) Vctr (3, 8, 16, 21) Connection Inductance (Lbonding) = 0.4nH Inductance (Lbonding) = 0.4nH Inductance ~ 1nH Inductance ~ 1nH External capacitor
C1 ~ 100pF C2 ~ 10nF C3 ~220 nF C1 ~ 100pF
