18 GHz to 44 GHz, GaAs, pHEMT, 32 dBm (>1 W), MMIC Power Amplifier

ADPA7005AEHZ

The ADPA7005 is a gallium arsenide (GaAs), pseudomorphic high electron mobility transfer (pHEMT), monolithic microwave integrated circuit (MMIC), 32 dBm saturated output power (PSAT), >1 W, power amplifier, with an integrated temperature compensated, on-chip power detector that operates between 18 GHz and 44 GHz. The ADPA7005 provides 15.5 dB of small signal gain and approximately 32 dBm of PSAT at 32 GHz from a 5 V supply (see Figure 26 in the data sheet). The ADPA7005 has an output IP3 of 40 dBm between 24 GHz to 34 GHz and is ideal for linear applications such as electronic countermeasure and instrumentation applications requiring >30 dBm of efficient PSAT. The RF input and outputs are internally matched and dc blocked for ease of integration into higher level assemblies. The ADPA7005 is packaged in a 7 mm × 7 mm, 18‑terminal ceramic leadless chip carrier with heat sink (LCCHS) that exhibits low thermal resistance and is compatible with surface-mount manufacturing techniques.

ADPA7005CHIP

The ADPA7005CHIP is a gallium arsenide (GaAs), pseudomorphic high electron mobility transistor (pHEMT), monolithic microwave integrated circuit (MMIC), distributed power amplifier that operates from 20 GHz to 44 GHz. The amplifier provides 17 dB of small signal gain, 30.5 dBm output power for 1 dB compression (P1dB), and a typical output third-order intercept (IP3) of 41 dBm. The ADPA7005CHIP requires 1200 mA from a 5 V supply on the supply voltage (VDD) and features inputs and outputs that are internally matched to 50 Ω, facilitating integration into multichip modules (MCMs). All data is taken with the chip connected via two 0.025 mm wire bonds that are at least 0.31 mm long.
