Product details
Overview
HMC452ST89 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 P1dB and +49 dBm OIP3 at 2.1 GHz with 9 dB gain and 50% PAE under +5 V supply. It serves as a final-stage RF power amplifier in cellular infrastructure and fixed wireless transmitters.
For engineers reviewing the HMC452ST89 datasheet, HMC452ST89 pinout, HMC452ST89 application, or HMC452ST89 equivalent, key selection criteria include broadband gain flatness across 400–2100 MHz, high linearity for CDMA2000/W-CDMA modulation, thermal performance up to +85°C, and SOT-89 package compatibility with standard RF layout practices.
Technical Context
The HMC452ST89 integrates a two-stage InGaP HBT amplifier topology optimized for high output IP3 and power-added efficiency across multi-band operation. Its DC-coupled RFIN and RFOUT pins require external matching networks per band-verified at 400 MHz, 900 MHz, 1900 MHz, and 2100 MHz-with bias applied directly to RFOUT.
Performance is stabilized over temperature via inherent HBT process characteristics, with gain variation ≤0.02 dB/°C and junction-to-paddle thermal resistance of 24.1 °C/W. The device operates within –40°C to +85°C ambient, supported by MSL1 packaging and Class 1A ESD rating.

Pinout & Package
SOT-89 package with exposed paddle for thermal management; requires soldering all ground pins (2, 4) and paddle to PCB RF ground plane using ≥6 thermal vias.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RFIN | DC-coupled RF input; requires off-chip 50 Ω matching network (e.g., C1/L1 per 400 MHz circuit). |
| 2 | GND | RF and DC ground reference; must be low-inductance connection to solid ground plane. |
| 3 | RFOUT | RF output and DC bias node; supplies Vcc to output stage; requires off-chip output matching (e.g., L4/C5/C6). |
| 4 | GND | Secondary ground terminal; symmetric layout with Pin 2 ensures balanced grounding for stability. |

FAQ
What is the recommended DC bias configuration for HMC452ST89?
The HMC452ST89 uses a single +5 V supply applied to Pin 3 (RFOUT), which serves as both RF output and DC bias node for the output stage. Input stage bias is internally set; no external gate/base bias resistors are needed. Decoupling capacitors (C6, C7) must be placed near Pin 3 per the 400 MHz application circuit.
Does HMC452ST89 require external matching components?
Yes, the HMC452ST89 is DC-coupled on both RFIN (Pin 1) and RFOUT (Pin 3) and requires off-chip matching networks for impedance transformation to 50 Ω. Application circuits for 400 MHz, 900 MHz, 1900 MHz, and 2100 MHz are provided in the datasheet, specifying exact capacitor and inductor values.
What thermal management is required for reliable operation of HMC452ST89?
The HMC452ST89 has a junction-to-paddle thermal resistance of 24.1 °C/W and must be mounted with the exposed paddle soldered to a large copper ground plane using ≥6 thermal vias. For continuous operation at +85°C ambient, derating is required above 2.7 W dissipation, and forced-air cooling or heatsinking is recommended above 2 W.
Is HMC452ST89 pin-compatible with HMC452ST89E?
Yes, the HMC452ST89 and HMC452ST89E share identical pinout, electrical specifications, and SOT-89 mechanical outline. The only difference is RoHS compliance: HMC452ST89E uses 100% matte tin lead finish and 260°C peak reflow, while HMC452ST89 uses Sn/Pb and 235°C reflow.
Can HMC452ST89 operate at 3.5 GHz for CBRS applications?
No, the HMC452ST89 is characterized and specified only from 0.4 to 2.2 GHz. At 3.5 GHz, gain drops below 3 dB and OIP3 degrades significantly; it is not validated for CBRS band operation. For 3.5 GHz, consider Analog Devices' HMC451LP3E or Qorvo QPL9057 instead.
