The O243 is a 1.2 ~ 1.4GHz GaAs monolithic integrated power amplifier chip that provides 22dB power gain and 26dBm saturated output power at +5 V operating voltage with 36% power added efficiency. The power amplifier chip using on-chip through-hole metallization process to ensure a good grounding, no additional grounding measures, easy to use. The back of the chip was metallized, suitable for eutectic sintering or conductive adhesive bonding process.
