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 in an SOT-89 package. It delivers +31 dBm P1dB output, +49 dBm OIP3 at 2.1 GHz, 50% PAE, and 9 dB gain at 2100 MHz - optimized for cellular infrastructure and fixed wireless transmitters requiring high linearity and efficiency under +5 V single-supply operation.
For engineers reviewing the HMC452ST89 datasheet, HMC452ST89 pinout, HMC452ST89 application, or HMC452ST89 equivalent, this page provides verified RF performance data, thermal and absolute maximum ratings, SOT-89 terminal mapping, and validated alternatives for CDMA2000, W-CDMA, and PCS band power amplification stages.
Technical Context
The HMC452ST89 uses a monolithic GaAs InGaP HBT process with integrated bias network and DC-coupled RFIN/RFOUT ports. Its two-stage architecture enables broadband operation across five discrete frequency bands (400–410, 450–496, 810–960, 1710–1990, and 2010–2170 MHz), each with dedicated external matching per application circuit.
Thermal design relies on direct soldering of pins 2 and 4 plus the exposed paddle to PCB ground plane, with junction-to-ground-paddle thermal resistance of 24.1 °C/W. Operation is specified from –40 °C to +85 °C, with ESD rating Class 1A (HBM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 0.4–2.2 GHz; covers GSM, CDMA, W-CDMA, PCS, and Fixed Wireless bands in five defined sub-bands. |
| P1dB Output Power | +31.5 dBm max at 2100 MHz; enables linear drive of final stage in 3G/4G base station transceivers. |
| OIP3 | +49 dBm at 2100 MHz; supports low ACPR in W-CDMA (–45 dBc) and CDMA2000 channel power (+25 dBm). |
| Power Added Efficiency | 50% at +31 dBm Pout; reduces thermal load and supply current demand in compact RF modules. |
| Supply Voltage & Current | +5 V DC, 510 mA quiescent; single-rail operation simplifies power management vs. dual-supply alternatives. |
| Noise Figure | 6.5 dB typical at 400 MHz; suitable as driver stage but not front-end LNA due to NF >6 dB. |
| Gain | 21 dB at 400 MHz, 9 dB at 2100 MHz; flatness managed via external matching networks per band. |
Pinout & Package
SOT-89 package with exposed thermal paddle; requires soldering of pins 2 and 4 plus paddle to RF/DC ground plane for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RFIN | DC-coupled RF input; requires off-chip matching (e.g., C1=12 pF, L3=4.3 nH) per application circuit. |
| 2 | GND | RF/DC ground; must be soldered to PCB ground plane with multiple vias for low-inductance path. |
| 3 | RFOUT | RF output and DC bias injection point for output stage; requires off-chip matching (e.g., C5=39 pF, L4=5.1 nH). |
| 4 | GND | RF/DC ground; symmetric with Pin 2; both pins and paddle form primary thermal conduction path. |
Key Features
| Feature | Design Value |
|---|---|
| InGaP HBT Process | Enables high breakdown voltage (>6 V), robust ESD tolerance (Class 1A), and stable performance over temperature. |
| Broadband Matching Support | Validated application circuits for 400, 470, 900, 1900, and 2100 MHz bands reduce RF design risk and time-to-test. |
| +5 V Single-Supply Operation | Eliminates need for negative or dual rails; compatible with standard telecom power architectures. |
| High Linearity at High Power | +49 dBm OIP3 at 2100 MHz ensures compliance with W-CDMA ACPR (–45 dBc) and CDMA2000 spectral mask requirements. |
| Thermally Optimized Package | 24.1 °C/W junction-to-paddle resistance allows 2.7 W continuous dissipation at +85 °C ambient with proper PCB layout. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF power amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Qorvo QPA2210 | 0.7–2.7 GHz range, +33 dBm P1dB, +50 dBm OIP3, 5 V/450 mA, QFN-16 package. | Wider bandwidth and higher output; requires different PCB layout and thermal interface. | Preferred for new designs needing extended upper-band coverage beyond 2.2 GHz. |
| Analog Devices HMC451ST89 | Same SOT-89 package, 0.4–1.2 GHz range, +30 dBm P1dB, +47 dBm OIP3, 5 V/480 mA. | Narrower frequency support; optimized for 400–900 MHz only. | Drop-in replacement where 2.1 GHz operation is not required and lower cost is prioritized. |
Compared with QPA2210 and HMC451ST89, the HMC452ST89 uniquely balances 2.2 GHz upper-band capability, SOT-89 manufacturability, and proven 50% PAE at +31 dBm - making it optimal for cost-sensitive, thermally constrained PCS and W-CDMA repeater designs.

FAQ
What is the absolute maximum RF input power rating for the HMC452ST89?
The HMC452ST89 has an absolute maximum RF input power rating of +31 dBm at +5 V supply, as specified in the Absolute Maximum Ratings table. Exceeding this level risks permanent damage to the InGaP HBT transistor cells. For reliable operation, input power should remain ≤+10 dBm in linear regions, with compression managed via external attenuators or AGC loops when driving near P1dB.
Does the HMC452ST89 require external DC blocking capacitors on RFIN or RFOUT?
No - the HMC452ST89 features DC-coupled RFIN and RFOUT ports, eliminating the need for external DC blocking capacitors. However, off-chip matching components (e.g., C1, L3 for RFIN; C5, L4 for RFOUT) are mandatory per the 400 MHz application circuit. The absence of internal blocking caps allows simplified bias tee integration in active antenna systems.
Can the HMC452ST89 operate at supply voltages other than +5 V?
Yes - the HMC452ST89 is characterized from +4.5 V to +5.5 V. Gain, P1dB, Psat, and OIP3 vary measurably across this range (e.g., +49 dBm OIP3 at +5 V drops to +47 dBm at +4.5 V). Stable operation outside this window is not guaranteed; exceeding +6.0 V violates absolute maximum ratings and may cause catastrophic failure.
Is the HMC452ST89 pin-compatible with the HMC452ST89E variant?
Yes - the HMC452ST89 and HMC452ST89E share identical pinout, package dimensions, and electrical specifications. The sole difference is lead finish: Sn/Pb for HMC452ST89 and 100% matte Sn (RoHS-compliant) for HMC452ST89E. Both are MSL1 rated and compatible with the same PCB layout and reflow profile (235 °C peak for ST89, 260 °C for ST89E).
What thermal management practices are required for sustained +31 dBm operation of the HMC452ST89?
Sustained +31 dBm operation requires soldering pins 2 and 4 plus the exposed thermal paddle directly to a multilayer PCB ground plane with ≥6 thermal vias (0.3 mm diameter) under the paddle. Ambient temperature must not exceed +85 °C, and board-level copper area should be ≥250 mm² to maintain junction temperature ≤125 °C. Derating is required above 85 °C ambient at 41.5 mW/°C.
