Product details
Overview
HMC589ST89 from Hittite Microwave Corporation (now part of Analog Devices) is an InGaP HBT MMIC gain block amplifier operating from DC to 4 GHz in a SOT-89 package, delivering 21 dB small-signal gain, +21 dBm P1dB output power, and +33 dBm OIP3 at 1 GHz - used as a cascadable 50 Ω RF/IF gain stage or LO/PA driver in cellular/3G, microwave radio, and test equipment.
For engineers reviewing the HMC589ST89 datasheet, HMC589ST89 pinout, HMC589ST89 application, or HMC589ST89 equivalent, this page provides verified specifications, thermal stability data, biasing guidance, and real-world application context for RF front-end design, driver-stage selection, and broadband gain block replacement.
Technical Context
The HMC589ST89 employs an InGaP HBT process enabling stable DC–4 GHz operation with minimal gain variation (0.008 dB/°C) and robust thermal performance across –40°C to +85°C. It operates from a single +5 V supply drawing 82 mA quiescent current, with internal biasing optimized via external RBIAS (1.8 Ω) for temperature-stable ICQ.
Its 3-pin SOT-89 configuration integrates RF input (Pin 1), RF output/DC bias feed (Pin 3), and dual ground terminals (Pins 2 & 4). Input/output return loss exceeds 13 dB (DC–1 GHz) and 8 dB (1–4 GHz), supporting broadband 50 Ω system integration without matching networks in many applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| P1dB Output Power | +21 dBm at 0.5–1.0 GHz - enables direct drive of medium-power PA stages or mixer LO ports without additional amplification. |
| Small-Signal Gain | 21 dB at DC–1.0 GHz - provides consistent cascaded gain with <±2 dB flatness up to 2 GHz for multi-stage RF chains. |
| OIP3 | +33 dBm at 1 GHz (0 dBm/tone, 1 MHz spacing) - supports linear operation in FWA and CATV upstream paths with low intermodulation distortion. |
| Noise Figure | 4.0 dB (DC–2.0 GHz) - suitable for IF/RF gain-before-mixer roles where SNR preservation is critical. |
| Supply Current | 82 mA @ +5 V - enables low-power biasing with standard LDOs; dissipation remains within 0.41 W at TA = +85°C. |
| Operating Temperature | –40°C to +85°C - validated for industrial and outdoor wireless infrastructure environments. |
| Gain Stability | 0.008 dB/°C over DC–5 GHz - ensures predictable gain across thermal cycling without recalibration. |
Pinout & Package
Package: Industry-standard SOT-89 (3-lead, surface-mount), molded plastic body with exposed ground paddle; RoHS-compliant version HMC589ST89E uses matte tin plating (MSL1, 260°C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RF Input (IN) | DC-coupled input requiring external blocking capacitor; matched to 50 Ω with >13 dB return loss up to 1 GHz. |
| 2, 4 | Ground (GND) | RF/DC ground terminals - must be soldered directly to PCB ground plane with multiple vias for low-inductance return path. |
| 3 | RF Output / VCC | Combined RF output and DC bias feed; requires external decoupling (C4 = 1000 pF) and bias choke (L1) per application circuit. |
Key Features
| Feature | Design Value |
|---|---|
| InGaP HBT Process | Enables high fT, excellent reliability, and stable gain/power over temperature without active bias compensation. |
| Broadband DC–4 GHz Operation | Eliminates need for band-specific amplifiers; supports multi-band base stations and wideband test instrumentation. |
| +33 dBm OIP3 at 1 GHz | Meets linearity requirements for 3G/4G uplink signals and cable modem DOCSIS 3.1 upstream channels. |
| Single +5 V Supply | Reduces power subsystem complexity; compatible with common system rails and eliminates negative supplies or charge pumps. |
| SOT-89 Package with Exposed Paddle | Provides 119 °C/W junction-to-ground thermal resistance - enables operation at full P1dB without heatsink in moderate airflow. |
Applications
| Cellular Base Station IF Chain | Fixed Wireless Access (FWA) Transceiver |

Equivalent & Alternatives
The following parts are listed as comparable options for similar gain block applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Qorvo QPL9057 | Higher gain (23 dB), wider bandwidth (DC–6 GHz), but higher NF (4.5 dB) and +5.5 V supply requirement. | Better suited for 5G FR1 front ends requiring extended upper frequency coverage beyond 4 GHz. | Select QPL9057 only if >4 GHz bandwidth or >22 dB gain is required; verify PCB layout compatibility with different SOT-89 footprint. |
| Analog Devices HMC441ST89 | Lower P1dB (+18 dBm), same 21 dB gain, +32 dBm OIP3, but optimized for +3 V operation (65 mA). | Preferred for battery-powered portable test gear where supply voltage headroom is constrained. | Choose HMC441ST89 when +3 V rail is mandatory and +18 dBm output suffices; note reduced output power limits dynamic range. |
Compared with QPL9057 and HMC441ST89, the HMC589ST89 delivers optimal balance of +21 dBm output, +33 dBm linearity, and +5 V simplicity for fixed infrastructure RF designs - making it preferred for cost-sensitive, thermally stable, broadband gain applications below 4 GHz.

FAQ
What is the recommended bias resistor value for HMC589ST89 at +5 V supply?
The HMC589ST89 requires an external bias resistor (RBIAS) to stabilize collector current over temperature. At +5 V supply, the recommended value is 1.8 Ω, rated for 1/8 W, yielding 82 mA ICQ. This value is validated in the datasheet for optimal P1dB and OIP3 performance across –40°C to +85°C.
Does HMC589ST89 require external DC blocking capacitors?
Yes, the HMC589ST89 requires external DC blocking capacitors on both RF input (Pin 1) and RF output (Pin 3) because its IN and OUT pins are DC-coupled. Typical values are 100 pF for 900 MHz+ operation and 0.01 μF for sub-100 MHz use, as specified in the application circuit.
Is HMC589ST89 still in production or obsolete?
The HMC589ST89 is marked "OBSOLETE" in the official datasheet revision v04.0710. However, Aetrix Electronics maintains legacy inventory and offers lifecycle availability coordination, including last-time-buy planning and cross-reference support for qualified replacements like HMC441ST89.
What is the thermal resistance and maximum junction temperature of HMC589ST89?
The HMC589ST89 has a junction-to-ground thermal resistance of 119 °C/W and a maximum junction temperature of 150 °C. With 82 mA at +5 V (0.41 W dissipation), junction temperature rise is ~49 °C above board temperature - allowing reliable operation at +85 °C ambient when properly mounted to a ground plane.
Can HMC589ST89 be used in 50 Ω cascade configurations without matching networks?
Yes, the HMC589ST89 is designed for direct 50 Ω cascade use: input return loss exceeds 13 dB (DC–1 GHz) and output return loss exceeds 8 dB (DC–1 GHz), enabling multi-stage RF chains with minimal external components. Matching is only needed for narrowband optimization or impedance transformation outside 50 Ω.
