Product details
Overview
HMC452QS16G from Analog Devices (formerly Hittite Microwave) is a GaAs InGaP HBT 1 W MMIC power amplifier operating from 0.4 to 2.2 GHz, delivering 31 dBm saturated output power and +48 dBm OIP3 at 2.1 GHz with 53% PAE at +31 dBm Pout, optimized for cellular infrastructure and fixed wireless transmitters.
For engineers reviewing the HMC452QS16G datasheet, HMC452QS16G pinout, HMC452QS16G application, or HMC452QS16G equivalent, key selection criteria include its 22.5 dB gain at 400 MHz, integrated VPD power control, QSOP16G SMT package, and single +5 V supply operation in multi-band RF front-end designs.
Technical Context
The HMC452QS16G employs a monolithic GaAs InGaP HBT process enabling high linearity and efficiency across 0.4–2.2 GHz. Its two-stage architecture integrates input/output matching networks requiring only external DC blocking and bias components, with VPD pin enabling precise control of quiescent current and RF output power.
It operates with fixed +5 V collector bias and supports temperature-stable performance: gain variation ≤0.02 dB/°C, and maintains ≥7 dB noise figure up to 2.17 GHz. The device is designed for broadband linear amplification in FDD/TDD base station and repeater applications where high OIP3 and low ACPR are critical.

FAQ
What is the maximum RF input power rating for the HMC452QS16G?
The HMC452QS16G has an absolute maximum RF input power rating of +31 dBm when Vs = Vpd = +5 Vdc, as specified in the Absolute Maximum Ratings table. Exceeding this level risks permanent damage to the InGaP HBT transistor junctions, especially under mismatched load conditions.
Does the HMC452QS16G require external matching components?
Yes, the HMC452QS16G requires external matching components on both RFIN (Pin 6) and RFOUT (Pins 11–12) to achieve optimal 50 Ω impedance transformation across its 0.4–2.2 GHz operating range. Application circuits specify discrete L/C values validated for 400 MHz, 900 MHz, and 2100 MHz bands.
What is the thermal resistance and recommended PCB layout for the HMC452QS16G?
The HMC452QS16G has a junction-to-ground-paddle thermal resistance of 24.1 °C/W. The exposed paddle and all GND pins (1, 2, 4, 5, 7–10, 13–16) must be soldered to a solid RF ground plane with multiple thermal vias to maintain junction temperature below 150 °C at full power.
Can the HMC452QS16G operate from a supply voltage other than +5 V?
The HMC452QS16G is characterized and optimized for +5 V DC operation. While functional at 4.5–5.5 V per gain/power/IP3 vs. supply voltage plots, operation outside +5 V reduces PAE and shifts P1dB/OIP3; the absolute maximum collector bias is +6.0 Vdc.
Is the HMC452QS16G pin-compatible with the HMC452QS16GE?
Yes, the HMC452QS16G and HMC452QS16GE share identical pinout, package dimensions, and electrical specifications. The only differences are lead finish (Sn/Pb vs. 100% matte Sn) and MSL reflow profile (235 °C vs. 260 °C peak), making them drop-in replacements in compatible assembly processes.
