GENERAL DESCRIPTION The ADL7003 is a gallium arsenide (GaAs), pseudomorphic high electron mobility transistor (pHEMT), monolithic microwave integrated circuit (MMIC), balanced low noise amplifier that operates from 50 GHz to 95 GHz. In the lower band of 50 GHz to 70 GHz, the ADL7003 provides 14 dB (typical) of gain, 21 dBm output IP3, and 12 dBm of output power for 1 dB gain compression. In the upper band of 70 GHz to 90 GHz, the ADL7003 provides 15 dB (typical) of gain, 21 dBm output IP3, and 14 dBm of output power for1 dB gain compression. The ADL7003 requires 120 mA from a 3 V supply . The ADL7003 amplifier inputs/outputs are internally matched to 50 Ω, facilitating integration into multichip modules (MCMs). All data is taken with the chip connected via one 0.076 mm (3 mil) ribbon b ond of 0.076 mm (3 mil) minimal length.

Rev. 0 | Page 13 of 18 THEORY OF OPERATION The architecture of the ADL7003 low noise amplifier is shown in Figure 38. The ADL7003 uses two cascaded four-stage amplifiers operating in quadrature between two 90° hybrids. This balanced amplifier approach forms an amplifier with a combined gain of 14 dB and a saturated output power (PSAT) of 18 dBm. The 90° hybrids ensure that the input and output return losses are greater than or equal to 15 dB. See the application circuit shown in Figure 41 for further details on biasing the various blocks. RFIN RFOUT 15691-037 Fi gure 38. ADL7003 Architecture
The ADL7003 is a GaAs, pHEMT, MMIC power amplifier. and VGG34A, and use capacitive bypassin g as shown in Figure 41. the assembly diagram (Figure 42).
- Set the gate bias voltage to −1.5 V.
- Set all the drain bias voltages, VDD = 3 V.
- Increase the gate bias voltag e to achieve a quiescent
- Decrease the gate bias voltage to −1.5 V to achieve

Rev. 0 | Page 15 of 18 Handling Precautions To avoid permanent damage, follow these storage, cleanliness, static sensitivity, transient, and general handling precautions:
- Place all bare die in either waffle or gel-based ESD protective containers and then seal the die in an ESD protective bag for shipment. After the sealed ESD protective bag is opened, store all die in a dry nitrogen environment.
- Handle the chips in a clean environment. Do not attempt to clean the chip using liquid cleaning systems.
- Follow ESD precautions to protect against ESD strikes.
- While bias is applied, suppress instrument and bias supply transients. Use shielded signal and bias cables to minimize inductive pickup.
- Handle the chip along the edges with a vacuum collet or with a sharp pair of bent tweezers. The surface of the chip may have fragile air bridges and must not be touched with vacuum collet, tweezers, or fingers. Mounting Before epoxy die is attached, apply a minimum amount of epoxy to the mounting surface so that a thin epoxy fillet is observed around the perimeter of the chip after it is placed into position. Cure the epoxy per the schedule of the manufacturer. Wire Bonding RF bonds made with 0.003 in. × 0.0005 in. gold ribbon are recommended for the RF ports. These bonds must be thermo- sonically bonded with a force of 40 g to 60 g. DC bonds of 0.001 in. (0.025 mm) diameter, thermosonically bonded, are recommended. Create ball bonds with a force of 40 g to 50 g and wedge bonds with a force of 18 g to 22 g. Create all bonds with a nominal stage temperature of 150°C. Apply a minimum amount of ultrasonic energy to achieve reliable bonds. Keep all bonds as short as possible, less than 12 mil (0.31 mm). Alternatively, short (≤3 mil) RF bonds made with two 1-mil wires can be used.
The drain and gate voltages can be applied to either the north or the south side of the circuit. Figure 41. Typical Application Circuit
