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 50% PAE, optimized for cellular/PCS/3G base station and fixed wireless transmit stages.
For engineers reviewing the HMC452ST89 datasheet, HMC452ST89 pinout, HMC452ST89 application, or HMC452ST89 equivalent, key selection criteria include broadband gain flatness (7–21 dB across band), single +5 V supply operation, SOT-89 package thermal performance, and verified W-CDMA/CDMA2000 linear power capability.
Technical Context
The HMC452ST89 integrates a two-stage InGaP HBT amplifier with DC-coupled input and RF output bias feed, requiring external matching networks per frequency band. It operates with fixed +5 V collector bias and draws 510 mA quiescent current, enabling high linearity without complex bias sequencing.
Its architecture supports wideband operation via impedance-tuned microstrip traces (e.g., TL1–TL5 in 400 MHz circuit), with thermal design anchored to the exposed paddle and four ground pins-enabling stable 2.7 W dissipation at +85 °C with 24.1 °C/W junction-to-ground thermal resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 0.4–2.2 GHz: Full-band operation validated across five discrete bands (400–410, 450–496, 810–960, 1710–1990, 2010–2170 MHz). |
| P1dB Output Power | +31.5 dBm max @ 2.1 GHz: Enables 28–31 dBm linear output across bands, supporting CDMA2000 +25 dBm channel power at –45 dBc ACP. |
| OIP3 | +49 dBm @ 2.1 GHz: Delivers high third-order intercept for multi-carrier W-CDMA and LTE uplink linearity. |
| Power Added Efficiency | 50% @ +31 dBm Pout: Reduces thermal load and DC power consumption in compact RF front-ends. |
| Gain | 21 dB @ 400 MHz / 9 dB @ 2100 MHz: Band-dependent small-signal gain enables flexible system-level gain distribution. |
| Noise Figure | 6.5 dB typical @ 400 MHz: Supports cascaded noise budgeting in receive-path shared modules or TDD transceivers. |
| Supply Current | 510 mA @ +5 V: Fixed bias simplifies power management; no gate voltage tuning required. |
Pinout & Package
SOT-89 package with exposed thermal paddle and four terminals: Pin 1 (RFIN), Pin 2 (GND), Pin 3 (RFOUT/Vcc), Pin 4 (GND). Requires soldering all ground pins and paddle to PCB RF ground plane for thermal and RF stability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RFIN | DC-coupled RF input; requires off-chip matching network (e.g., C1/L1 in 400 MHz circuit) for 50 Ω interface. |
| 2, 4 | GND | RF and DC ground return paths; must be low-inductance connections to PCB ground plane and thermal paddle. |
| 3 | RFOUT / Vcc | RF output and DC bias feed point; requires off-chip RF choke (L3/L4) and bypass (C5/C6) for stable bias and harmonic suppression. |
Key Features
| Feature | Design Value |
|---|---|
| InGaP HBT Process | Enables high fT/fmax, robust ESD tolerance (Class 1A), and stable performance over –40 to +85 °C. |
| Single +5 V Operation | Eliminates dual-rail supplies; simplifies board layout and reduces BOM count in cost-sensitive infrastructure designs. |
| Thermal Design | 24.1 °C/W junction-to-ground thermal resistance supports 2.7 W continuous dissipation at +85 °C ambient. |
| Band-Specific Matching | Validated application circuits provided for 400, 470, 900, 1900, and 2100 MHz bands-enabling rapid integration without EM simulation. |
| W-CDMA/CDMA Linearity | +25 dBm channel power at –45 dBc ACPR (64 DPCH, 2.14 GHz) confirms suitability for 3GPP-compliant base station PA stages. |

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 QPA2211 | 0.7–2.7 GHz GaN HEMT PA; +34 dBm P1dB, +52 dBm OIP3, 28 V supply, higher efficiency but larger 5×5 mm QFN. | Targets higher-power macrocell base stations; not drop-in due to voltage, footprint, and bias complexity. | Select for >33 dBm output or >2.2 GHz extension; avoid for +5 V SOT-89 constrained designs. |
| Analog Devices HMC451LP3E | 0.4–2.5 GHz GaAs pHEMT; +28 dBm P1dB, +45 dBm OIP3, +5 V, 16-pin 3×3 mm LFCSP, integrated bias control. | Designed for digitally controlled bias and envelope tracking; requires additional control logic vs. HMC452ST89's fixed bias. | Select when adaptive bias or digital interface is needed; HMC452ST89 preferred for analog-only, cost-sensitive deployments. |
Compared with QPA2211 and HMC451LP3E, the HMC452ST89 offers the lowest BOM count and smallest footprint for +5 V, 1 W-class linear amplification-making it optimal for space-constrained FWA and small-cell remote units where thermal management is prioritized over peak power.

FAQ
What is the recommended DC blocking and bypass capacitor configuration for HMC452ST89?
For HMC452ST89, use 12 pF (C1) and 15 pF (C2) 0402 capacitors at RFIN, 6.8 pF (C3/C4) and 39 pF (C5) at RFOUT, plus 100 pF (C6) and 2.2 μF tantalum (C7) for Vcc bypass. These values are validated in the 400 MHz application circuit and maintain impedance integrity across 0.4–2.2 GHz.
Does HMC452ST89 require external bias sequencing or temperature compensation?
No-HMC452ST89 operates with a single fixed +5 V supply and draws 510 mA quiescent current. Its InGaP HBT process provides inherent thermal stability, with gain variation of only 0.012–0.02 dB/°C across all bands; no external bias control or compensation circuitry is needed.
Can HMC452ST89 be used in TDD systems alongside receiver LNA stages?
Yes-HMC452ST89's 6.5 dB noise figure at 400 MHz and high reverse isolation (>10 dB across band) allow co-location with LNAs in TDD architectures. Its 22 dB input return loss minimizes LO leakage impact, and the SOT-89 package supports tight RF shielding integration.
What is the maximum RF input power rating for HMC452ST89 before damage occurs?
HMC452ST89 has an absolute maximum RF input power rating of +31 dBm at +5 V supply. Exceeding this level risks permanent degradation of the InGaP HBT transistor; system design must include input limiting or circulator protection in high-PIN environments.
Is HMC452ST89 RoHS-compliant and compatible with lead-free reflow?
The HMC452ST89 variant is Sn/Pb solder-finished and rated MSL1 with 235 °C peak reflow; the RoHS-compliant HMC452ST89E uses 100% matte tin and supports 260 °C peak reflow. Both require strict ESD handling (Class 1A) and grounding of all GND pins and paddle during assembly.
